Jitter computation using the power and phase spectra of the PAM signals: Comparison with results obtained by simulation
Abstract
A theoretical jitter model for a regenerative repeater timing circuit is described. A method for jitter calculation is derived consisting of a frequency domain analysis based on a particular definition of the phase spectra of the pulse amplitude modulation signals which show random characteristics. A particular case characterized by binary sequences with independent and equiprobable symbols, and with equalized pulse shape given by an analytical expression is examined. The rms jitter value is calculated for various Q factors and syntony errors. Comparison with results from computerized simulation shows quantitative differences which are larger for higher Q factors and syntony errors.
