Brad:
You are treating an FFT as if it were a spectrum analyzer which produces a
magnitude or energy profile of how much signal is at a particular
frequency. The FFT does much more than that. It tells not only what
magnitude is at a frequency but what phase angle the signal has there.
Let's tak

I can't wrap my head around why fft transform of complex signal produces a complex output. After all the output reflects the amount of energy per frequency bin and frequency bins and energy are both real numbers, no?I'm trying to write a python script to analyze the energy across frequency bins but
