So I was playing with the FFT function( fast Fourier transform, it should be a good proxy for a spectrum analyzer so I tried one kHz sine waves from my small function generator we've got the following wave form
then I change the function to a square wave to see the harmonics.
I was wondering if there are any tricks to improve the resolution of this display?
