We now have to make some assumptions about the characteristic of the jitter to proceed. One assumption that seems to work is that the jitter amplitude has a Gaussiandistribution. For a jitter waveform that has a Gaussian distribution, there is a point on the Gaussian jitter distribution curve that reflects the RMS value of jitter for Gaussian distribution waveforms, just as with the wave.
