Hi everyone,
As shown in figure, a strictly periodic waveform, x1(t), contains zero crossings that are evenly spaced in time. Now consider the nearly periodic signal x2(t), whose period experiences small changes, deviating the zero crossings from their ideal points, which is suffering from jitter. (Plotting the total phase, δtotal, and the excess phase, δexcess, of the two waveforms, we observe that jitter manifests itself as variation of the access phase with time). Can anyone please explain to me what the bracket sentence means? And what is the meaning and difference of total phase and excess phase? How do calculate and plot the total and excess? Appreciate if anyone could answer my questions, thanks....
