>>11470456I don't know much about math or radio but here's my take.
A negative amplitude doesn't mean anything particularly special in a pure mathematics case. It has some implications in radio theory though, such as amplitude modulation obviously.
The negative amplitudes on graph above are just points on the unit circle or quadrature of the function in a Cartesian-plane, rather than, say, a polar coordinate plane.
The origin of a wave function and the magnitude of the quadrature are ultimately what determine if a given amplitude is negative.
So a negative amplitude just means that the sample is in a negative quadrant on a circle.
In conclusion, I'm just trying to seem smart in this post and I actually don't know what the fuck I'm talking about. lol
Good luck with your maths endeavors anon
