FFT Interpretation
Hello Skip, In regards to your two specific questions directed to me: 1. Yes, I am refering to anti-aliasing filters. The filter bandwidth has to be set such that you block all frequency components that you do not want aliased into your spectrum of interest. If you sample 3x only you need a...- maximizer

FFT Interpretation
Hi Skip, The "sidebands" that you are observing could be the result of sampling a square wave signal. The Fourier Transform of a square wave signal is a sin(x)/x function. Typical of this sin(x)/x function is that it has a main lobe centered at the frequency of the square wave signal...- maximizer
