Assume we have a simple AM signal, which is a mix of the carrier wave and upper/lower bands.
If I were to plot its time domain graph, I would get a graph with Y being its amplitude and X as time, similar to an oscilloscope graph. Let's call this graph A.
I can also plot a graph for its generated audio, with some software like "Audacity". This is graph B.
Is graph B the same as graph A? Are they identical? if not then how do they differ? What is their relation?
Why am I asking this question?
Question is related to software defined radio and demodulating RF signals. We can either sample the signal directly using IQ provided by the hardware, OR we could use its generated audio with software like multimon-ng. I'm trying to understand what's the difference between these two methods, is a signals audio the same as the signal itself?
