Correlation meaning the spurs share the same origin (source). For example, a square-wave has odd harmonics. If you see these harmonics in the FFT magnitude spectrum, you can tell they are correlated because each spur has the same phase-angle and they are integer multiples of the fundamental...

Hi Everyone, I am analyzing real data using fast-fourier transforms (FFT) in Matlab. The FFT magnitude spectrum show some background noise floor with several sharp spurs popping up high out of the background noise. I need to figure out conclusively which of these spurs are correlated with...
