    How to calculate periodic jitter from a spectrum of a signal

    Thanks for the tips. I am not sure if that is what I am looking for. I knew how to integrate the noise power spectrum to obtain the phase noise in either mUI or ps-rms. What I am looking for is kind of a special case I think where you got a carrier being FM modulate by a another signal at a...

    How to calculate periodic jitter from a spectrum of a signal

    I am trying to find a function that can calculate the periodic jitter given a power spectrum such as captured from a spectrum analyzer. For example, I have a 1.25GHz clock that is being FM modulated by another signal running at 1MHz. I can capture the power spectrum of the 1.25GHz on a spectrum...
