I got a job writing programs to model electrical signals. I'm gonna be honest, I don't know anything about the underlying math. I know how to go through the steps for Fourier and Laplace transforms. But I have no fucking idea what any if it means. And that's the extent of my knowledge. Anyone have any good sources where I can learn all about signals from scratch, given I have very basic digital electronics knowledge? Also friendly enough that a math brainlet can understand.
