All hail the Fourier Transform edition.

$\mathcal{F}\{ x(t) \} (\omega) = \int \limits_{-\infty}^{\infty} x(t) e^{-j \omega t}dt$

What are you working on now that you have free quarantine time, anon?
Im doing DFT implementations on matlab

Do you have one of those resistors that allows you to change the resistance? Use a fixed voltage battery to make a variable voltage battery with the breadboard.

make an astable multivibrator to flash 2 led lights, and from there, try to build a function generator which uses that circuit with op amps to create square triangle and sine waves. Try to design latches using a basic npn or n channel transistors. They are very basic circuits which can be made with a couple of resistors, capacitors and transistors or op amps.

definitely, especially if you're interested. i'm 25 in a month about to get my EE bachelors. i have friends on my course who are 28 and 32. i assume you're from the USA where getting a bachelors 1.5-2x's your income overnight (almost irregardless of degree). and with engineering this easily pays itself even if you take out a bunch of loans for it and got your degree at like 40.

"modern control" is control using state-space representation. i think it's better to start with classical control, of which this is a really good book, which is also free, http://www.cds.caltech.edu/~murray/amwiki/index.php/Second_Edition

after that you can move onto Ogata, and then a book on nonlinear control

My control systems lecturer is absolutely terrible. Is there something about this subject that draws exceptionally eccentric professors, even by EE standards. The two guys I've had have been head in the clouds, autistic weirdos who are obviously clever but can't teach to save their lives. Everyone in the class is completely confused, his coursework is completely jumbled and chaotic, his MATLAB code is all over the place.

The thing is I have looked at nearly all of Brian Douglas's control systems lectures on YouTube and it's obvious that it isn't actually any more difficult than my other classes, this lecturers is just an absolute clown.

I'm 23, about to go into my final year of Electronic & Computer Engineering.

If you're able for it, it's one of the best fields you can study in my opinion. I was like you, it definitely wasn't my passion in life and I wasn't one of those kids that spent all their time playing with electronics or programming. I was a jack of all trades in school, to be fair I was good at math and physics in comparison to my peers.

I've found it hard and it's going to take me 6 years to get a 4 year degree, but I honestly wouldn't have it any other way. I was a lazy student and if anything else, engineering has taught me how to grind and work hard. I also feel like it has made me much more analytically minded and objective in general, which is something gradual and you don't really notice happening.

I still wonder why you apply the Fourier operator on a fixed time evaluation of a function when you want to define a full frequency domain function. Are you sure you're not adding the "(t)" by mistake?

What are you trying to say? That you're applying the transform for a fixed value of t? x is a function of t so to leave that out would look like you're taking the transform of a variable. Is writing x(t) really any different than writing a function under an integral where the function argument is a variable in the limit of the integral?

If you don't want to do the same thing you're doing now for the rest of your life (or go into management I suppose), and you aren't learning anything new at your job (any job in-fact) you should leave. If they're paying for your masters though then it might be worth staying with them and trying to transfer to another department in the mean-time.

Seems this thread is dying im going to post a derivation of the impedance of a capacitor in frequency domain as a more interesting bump than just posting bump.

By Gauss's law we have that the current thru a capacitor with capacitance $C$ is:

$i_c(t) = C \frac{dv_c(t)}{dt}$

If we use the Laplace transform and asume a forced responce:

$I_c(s) = sCV_c(s) \\ <br /> \iff V_c(s) = \frac{1}{sC}I_c(s) \\<br /> \iff Z_c(s) = \frac{1}{sC} \square$

Lets do it for inductors too:

By Faraday's law, the voltage thru an inductor with inductance $L$ is:

$v_l(t) = L \frac{di_l(t)}{dt}$

If we use the Laplace transform and asume a forced responce:

$V_l(s) = sLI_l(s) \\<br /> \iff Z_l(s) = sL \square$

As an exercise see what happens if you let $\sigma = 0$ that is, the estationary state for an AC excitation.

Anything where the job description is mostly fluff. A lot of defense jobs (not the majority, but a larger portion than in any other industry) are like this. Small companies that do very repetitive work have a similar problem, but it's usually more of an issue at large companies where roles are very specific and tasks are significantly separated from the final product.

Holy double based, I'm doing the same. The thing about controls, as you know, is that it is totally ubiquitous with all areas of engineering and general science. It's even a /lit/ meme as per Nick Land's constant rumination of cybernetics. You can apply to literally every area of study conceivable the basic idea of feedback systems. The impression that I got, and have moreso now, is that there's no way you wouldn't be able to find a job in controls.

The Fourier operator acts on functions, not numbers, that's what I am trying to say. If x is a real valued function of t, x(t) is a real number, and F does not act on real. The notation does not make sense as is although everybody can understand it: it feels unrigorous, weird, and is probably not what is used as standard although you claim it is. Meanwhile, F{x} would make complete sense as F{x} is now a function with its own domain. And yes, bracket are unusual too but we can make do.

Yeah it's infuriating. Boomers have ruined the way of business and found ways to dissociate themselves from any sort of technical rigor and accountability. They just get the funding streams in place and channel capital to different vendors. Sometimes we'll contract a vendor who will then subcontract a vendor. We receive the final product, but between each level of accountability there's a paywall to communication in the form of support contracts. The SMEs at the other end will consciously withhold knowledge or deliver a broken product and make you pay up. The taxpayer is absolutely fleeced. I've seen 2-line code changes run the government $60k.

>>11539598
In the interview absolutely grill the hiring manager about what it is the group does and what you'll be doing. If they're wishy washy, that's the first red flag. Do not be scared to take conversations in a technical direction. Ask what degrees your coworkers have. If it's not engineering, math, or physics GTFO. Also, having engineering techs coded as engineers is another big red flag. The other post is right, be careful of very large companies working on DoD projects. They are thinly veiled defense welfare projects. I swear some of my coworkers are legitimately senile and should have retired long ago.

>>11539635
It's definitely financially and career-wise a very smart move. Especially if you want to get into DoD cleared work. That opens up a job market that is invisible to most. I actually am very excited about seeing what sort of controls work is out there. It is character building grinding at something you hate for a few years. Recalibrates your perspective. Makes the school grind feel enjoyable, valuable, and refreshing.

Electric Machinery
> A.E. Fitzgerald, Charles Kingsley and Stephen Umans - Electric Machinery. 6th and 7th Edition are pretty good.
> George McPhesrson and Robert Laramore - An Introduction to Electrical Machines and Transformers: This is an old book but it is nice, excellent if you want to delve deeper into electric machinery.
> Theodore Wildi - Electric Machinery, Drives and Power Systems. This delves into electric machines, electric drives and their relationship and impact on a whole power grid. Pretty good to get an overall view of a power system and electric machinery.

Power Systems:
> K. Y. Tang - Alternating Current Circuits. An amazing book for getting into the theme because it focuses on the basic analytic tools you will need to work with power systems
> Paul M. Anderson - Analysis of Faulted Power Systems. Focus on short-circuit analysis, open phase faults and power system stability during a contingency. Requieres knowledge about symmetrical components.
> Allen Wood, Bruce Wollenberg - Power Generation, Operation and Control. Excellent book to tackle how to operate and optimize, from an economic viewpoint, the electrical power generation.
> Hadi Saadat - Power System Analysis. Great book to get into the concepts of power systems and how to analyze those kind of systems on most situations. Just remember to do your own scripts instead of using the ones shown in the book.
> Olle Elgerd - Electric Energy System Theory: An Introduction. While it is an older book, it delves into perturbation analysis and optimization unlike any other book I have read so far.
> P. Kundur - Power Systems Stability and Control. I hate this book with a passion due to its organization, but handles some topics in a didactic way.
> A. A. Sallam, On P. Mallik - Power Systems Stability Modelling, Analysis and Control. Good book for understanding the models used for stability studies.

Sort of, my undergrad was really hard, more than usual, due it's bachelor being focused on power systems, and having a duration of 5 years; thanks to that I have knowledge in some topics that should be discussed during a Masters in other countries. To be honest, my forte lies in electric machinery, specifically electric drives, electric motor design and transformer analysis, and power electronics.

Honestly, I haven't thought about making a power systems study guide, even though I have helped two professors on their lectures and even dictated some of them. Maybe I will sort something out during the quarantine while I finish polishing and expanding my old class notes.

>Im also doing some project work for the company I work at and reading some stuff about tensors ive been meaning to check out for a long time.
I checked tensors just for the sake of it a long time ago, pretty interesting stuff I must say. I wish you luck if you tackle that in the future.

>I go to UNIMET bro, I have very mixed feelings for the uni. I always wanted to go to usb but when the time to apply came you couldnt even apply because they had shut down or something so I went to unimet.
Worry not, I won't judge you or anyone else for your university. Except those cunts from UCV, fuck those bastards with a rake. Sorry to hear that you couldn't make it here, but what can I say? The unis are suffering big time.

>Btw I know a ton of people that transferred from usb that study with me as well as many, many profs.
Yeah, many did. The students to not be held down by strikes and whatnot and the professors due to low salaries. Same old tale.

>My power systems prof was an unbearable cunt from your uni.
Let me guess, Aida Smith? Or was it someone else?

>Who taught sistemas electricos when you were there?
Based José Vivas, Based Miguel Martínez and Based Virgilio de Andrade. Gotta say, those profs, all of them now out of the country, were pretty good. We still have some good professors here at USB and some students and grad students are doing their best to help them out.

You should know at least one bare metal language that can compile to native binaries. C can accomplish anything from the lowest to highest level, from programming kernels to desktop applications. If you don't have a Python module for something, you often write it in C/C++ (Boost, for example).

I think it's terrible that students nowadays only learn Python.

As for skills, I have worked at a large company making $160k/year. All the top tier software companies like Amazon, Microsoft, Apple, Google pay similar.

But the people there don't know math. When they like to show off, they talk about math but they don't know as much as a math college graduate. They are wannabe mathematicians. What they are good at is being very familiar with their tools and programming languages, being able to absorb a lot of code in a short amount of time, and very good with algorithms.

If you know how to sort, trees, hashes, shortest path, string search, etc. you can easily get a job at those companies. Yet, I see so many H1-Bs there.

Do Americans hate those jobs? Why, if they pay so well? There is so much job anxiety, yet, when I tell people what company I worked for they always say "Oh, that company sucks."

Compared to what? And with that amount of salary, it can suck a little here and there, the hours can get a bit crazy.

Why aren't more Americans teaching themselves how to code? I know it's a meme by now, but why are there so many Chinese and Indians?

The argument that they get them cheap doesn't hold water, either. My American colleagues all got paid the same or less.

But as a prof shes utter shit, for example this trimestre she did this:
>Start off with 3-phase fault analysis
>she gives one (1) class on how to compute Zbus and how to expand it and shit
>expend next 5 weeks learning about symmetric components, to the point we completely forgot about how to do 3phase faults without sequence networks
>test coming up
>"study sequence networks and symmetrical components"
> Exam had literally 0 questions on symmetrical components
>A 12 point question was how to expand Zbus given a fault in the middle of the line and how to modify it given a new impedance added to a bar
>I wrote to just compute Ybus again and invert it and to compute the thevennin voltage with a new impedance on the affected bars
>she marks it wrong, says we were supposed to use the expansion method
>she made the specific remark that we shouldnt learn the methods on expanding Zbus as "just finding Ybus and inverting or computing thevennin is way easier"

It isn't. You are mistaking the function x(t) with a particular value of that function, say x(t*) ot x(t=t*) or basically x evaluated at some point. x(t) represents the signal (or function), NOT a value. that's why when defining a function you end it with x=x(t) or f=f(x), etc. The notation of OP is correct.

It's probably correct to distinguish between the value of the function and the function itself. If you are a software engineer like myself these differences are familiar, like passing a function pointer or invoking a function. If you have a strongly typed language, those differences are not just pedantic.

I can see why some people being pedantic can be annoying but it is also often a major source of confusion for newcomers to a subject. As many others, I've been diving (or trying to) into all kinds of subjects and realized how wrong the usage of the word "tensor" is in machine learning. Now that I have started learning general relativity and I actually am beginning to grasp what a tensor is, it seems to have nothing to do with a machine learning tensor anymore. They just used it for anything that can be represented as a higher dimensional matrix. It's as if they confused the notational device for the meaning of it. I didn't understand before why people were so confused by the term but now that I am starting to become a little less uneducated myself I can start to see why notational abuses can seriously throw off people, so it's probably good to be precise about terminology and notation until you know you're surrounded by people who will know what you mean from context.

I'm very smol brain in math, but maybe it's not so dumb to discuss these things. Sometimes notation is commonly misused and distinguishing between f and f(t) might be pedantic in some cases, but it doesn't seem so wrong. That is why there is often separate notation to make it explicit. Mathematical notation seems to be more context sensitive, but it also implies much more, sort of like a medium between a programming language and a natural language.

If everybody is in agreement if the function value or the function is meant, there is no issue here, no?

In any case, I'm not saying there isn't a distinction between the value of a function and the function itself. There is, that's why it's important to properfly define the function before taking it's transform or operating with it in any way; that's why I said, when you define the function x you normally end with x=x(t), so it's clear x(t) represents the function and something like x(t_0) represents a value of the function. Then it's perfectly valid to take the transform of x or x(t), since they are the same thing.

I'm not a sfotware engineering, however I have programmed in both C and C++, and I understand what you are saying (I think). In those languages at least if you define a function as something like f(int t), then when writing f(t) you would indeed be taking the value of that function when evaluated at t, and it would be totally different than writing f. However, that is like that because you're in a programming langugae and certain rules must be followed. It isn't the same in math. Think of it as being able to define a function as f(t) (int t*) that is, your function name is f(t). This might not be doable in C or C++, but is is perfectly valid to do so using mathematical language.

Btw you absolutely DO NOT know this but pay ranges from 300 to 800 usd a month + bonuses, for example if you bring your own laptop you instantly get a +20usd bonus per month.
Given your background Id expect a 400+usd salary, you need to be on the boss back in order for him to pay you tho.

They form the logic gates, flip flops and whatnot throughout combination of said components. I don't quite remember the schematics but I remember seeing them in one of my electronics/digital electronics book. "Lessons in Electric Circuits - Vol. 4 Digital" by Tony Kuphaldt. Basically they use transistors as a switch, mostly in saturation and cutoff to generate the logic signals. Remember that logic signals are mostly 0 and 1, represented on 0V and 5V, or any other low voltage to represent another state.

The lm386 has an open loop gain from 20 to 200. There likely is a great variance in where any given device will fall in this range. Since there is no feedback the amplitude will always be something between 20-200. There is no amplitude control. It's likely the input signal will just clip at the rails. It's much better to incorporate feedback, so there is a determined gain and if that gain needs to be something predictable the feedback will determine that.

I'm stuck on this problem with a voltage divider biased Npn transistor.

The professor wants us to recalculate VB, VE, VC, IE, IC, IB and Beta after flipping R1 and R2 for a circuit from a previous problem. But how can I determine if the divider is stiff or not without knowing the beta value? If it is stiff, I can solve for VB with the approximated formula, but otherwise I can't figure out how I'd calculate RIN(BASE) without knowing BetaDC.

Thanks, anon, the textbook says to compare RIN to R2, wasn't aware the relation holds for RE to R2, but certainly makes sense. But then theoretically, I'd end up with an undefined BDC, since IC/IB would be IC/0.

>>11545989
Well, he asked us to recalculate beta. I guess I can just assume it is 110 and then plug the currents back in to just confirm it? If there's no way to solve it without beta, I'm comfortable just providing the relationship like that. But it seemed like he wanted us to find a new beta value, which didn't make sense to me since we never calculated beta in the first place.

Yeah, I guess I misunderstood his question and thought there must be some way to solve for Beta or Rin without using that value he already gave us. But that wouldn't make sense fundamentally as the beta is determined by the transistor, and without him giving us some other value to work with, there would be no way to calculate it?

That's the only way I see to help you out with that. You could also try to build some stuff on your own with previous approval of your professor, given that you can get the components. Also, experiment with other possible things to do, a while ago I saw someone building a LED-iluminated d20, that should be a fun project to do.

I think you are wasting oxygen by breathing and should definitely go outside to take some sweet corona vibe. But on topic, you are lying, there is a strong distinction between functions and numbers. f(t) standardly represents the value of f evaluated at a t in its domain. There is a reason why we write f : t -> f(t). If you ever met a single math phd (which I highly doubt) who wrote this, they were probably in an informal context or studying more algebraic matters. It is acceptable to confuse f(t) with f, but that does not make it rigourously correct. Also, you are using an authority argument to make your point, wich makes you laughable on top on being retarded. I literally read dozens of books on functional analysis and advanced operator algebra where the distinction between what belongs to the field of scalar and what is a function is made on each fucking single page. These book were written by authorities too, but at least the reasoning behind would make sense and I would not use the fame of the authors as a proof that I am correct, you absolute mongoloid. In the case of polynomial rings, it is more acceptable to describe a polynomial by f(X) because the function behind the polynomial is not the same thing as the polynomial itself. But probably your two unconnected engineer neurons would fry trying to understand the difference, moron. You are the illustration why engineers are laughed at on a daily basis in academia.

I've read that a JFETs near their cutoff points are "square law devices". Does this literally mean I can use their amplification to solve the equation output=input^2 in analog? I'm asking because I've looked at how analog computers square numbers and its always sequence of op-amp logarithmic and antilogarithmic amplifiers. Why would people do that if they can get the same behavior from just a JFET and resistor?

now.... I know that formula Et or energy temperature equivalent goes like this

now for intrinsic concentration

and I get
ni=1.61*10^15K^[-3/2]cm^(-3)*340.15^[3/2]*e^(-10.91405)
now I am not sure what I need to get there as the correct result

electron concentration

Yes anon, in AM we usually use a circuit called Gilbert cell, composed of transistors, that gives an output of the form $v_o(x(t).y(t))$ . However, if x = y for all of your needs, then it's easier to use a FET, a MOSFET for example, because of that squared behaviour. But when you're dealing with op-amps you're simplifying a lot of stuff with respect to output/input impedances and currents, which are crucial for some circuits, specially in instrumentation and precision electronics.

Don't let the fundamentals determine your perception of the subject. It sounds like you're mostly talking about analog circuits, but I would hold off any judgement until you at least learn about op-amps, transistors, power electronics, oscillators, frequency response, stability, etc (not necessarily in their full depth, that would take a while, but at least learn what they are and what you can build with them). Personally, I'm not very interested in those topics either, but I still took the related classes and tried to learn them because I felt they could at least be useful in the future, even if I don't end up working in a field specifically related to those topics. Look into digital electronics and embedded systems if you have experience programming. They might interest you more since you have some experience.

Have you considered going into computer engineering? I did and have a career doing that all day (microcontroller firmware development). I've worked with a lot of EEs and they never get into programming the chips.

Don't listen to that retard, just do what you're interested in or you'll end up in the same place you are now. If you want to go back for EE then do it, but keep in mind if you want to be an engineer then you are going to need an accredited degree. If you're fine with programming then take an MIT OCW course and download the book off of libgen and follow along. You can finish a 1-2 semester long course in like a month.

Since all the reply’s were shit, I’ll give you a simpler answer. Are you aware what the transfer function of an op amp looks like? An op amp has a certain bandwidth defined by the location of the poles and zeroes of the op amp transfer function. If you have a signal that contains multiple frequency components, the op amp could gain up different frequencies by a different amount if it is not fast enough (not high enough bandwidth). This is called distortion (non linearity) as you are amplifying different frequency components by different amounts.

BJTs are used all over the place and are a fundamental building block you should understand. Moreso than FETs I'd argue as you don't need to know the inner works of a FET in an IC in order to use an IC. In a product my company makes we use an op-amp+transistor VCCS which uses a BJT as the element which linearly controls a the 4-20mA current output. There are also BJTs in our linear 10-32V to 5V homespun linear regulator circuits. You will run into them and will use them in your designs. You should know how they work.

For example, in pic related I don’t understand why we have |b - c|. Didn’t we just define y = c - b? So why is it that when we plug those values in for x and y in the triangle inequality, it becomes |b - c|? Or am I being a brainlet? I guess since we take the absolute value it doesn’t matter? Since |b - c| always equal to |c - b|?

Look up CMOS (complementary metal oxide semiconductor) logic. You dont need to know the physics. NMOS conduct with "high" input and PMOS conduct with "low" input.

Ignore the BJT replier. CMOS has no static current consumption (ignoring leakage) which allows chips with millions of logic gates to operate without overheating.

Essentially all modern digital are built using CMOS.

Another thing, building off this, is to look into the Pull Up Network and Pull Down Network. Since each transistor is only a switch, to avoid an ambiguous state you need to have the logic connected to the high and the opposite connected to the low.

brainlet the point is to get a intuition for an implementation of basic nand logic. once you understand how that works then it literally doesn't matter what implementation you have; mechanical, hydraulic, photonic, etc. PNP is the simplest way to understand a transistor, and BJT makes for an extremely simple NAND gate

What do you mean by "working on software"? do you wanna do websites? you don't need a degree to do that. Wanna do embedded systems? EE/CpE is way better than CS.

I don’t know enough to understand most of this, by it does seem to have incredible potential.

hey guys, I'm looking for books that focus on synchronous generators, the excitation system, and its controller. Any tips?

Try with the "Synchronous Machines: Theory and Performance" by C. Concordia. Other than that, an book about Electrical Drives or Electrical Machinery should be good enough to delve into the excitation system and its controller. Check out older posts from this thread, I posted some books about electrical machinery and control.

ME here....
Sorry EE fags

But I just wanted to say, the EE dept at my uni is full of tenured prof. who just fail the shit out of every class so it comes as no suprise that it would take >4 years to get a 4 year degree.

I actually don't know any EE who have not had a w on their transcript because they flatout failed a class.

Meanwhile, ME dept turns a blind eye to 90% of the cheating that goes on. It's no wonder ME kids get laughed at, and ones who graduate with high 3's still don't know what the fuck they are doing.

Goodluck, I know your shit isn't easy.

If anyone reads this, can I get some advice on pursuing a graduate degree? Like how should I choose my school/pathway. What benefits does it have aside from "make money". I want to work in research and development. Maybe I should work on perfecting my maths?

That depends on what you want to focus on. Most people will tell you to do a MBA to polish yourself for management positions, but that depends on you. Try to net a Masters degree and go from there if you want to focus on R&D.
Also, yes EE professors can be a cunt. One of my professors just outright failed the 40% of his class jus because.
