Analysis and Simulation of Jitter Sequences for Testing Serial Data Channels

Analysis of jitter influence in fast frequency measurements

“…All DJ subcomponents have a bounded peak-to-peak valué that does not increase when more measurement samples are taken [8].…”

“…In time domain, TJ is the sum of the RJ and DJ components [8]. RJ is characterized by a Gaussian distribution.…”

“…By the central limit theorem, the distribution of a large number of uncorrelated noise sources approaches a probability Gaussian distribution and is given by [7,8] …”

“…where PJ T denotes the total periodic jitter, n is the number of cosine components, a, is the amplitude in units of time in each tone, co¡ is the angular frequency of the corresponding modulation, t is the time, and 0, is the corresponding phase [8].…”

“…3a-d was independently constructed with data obtained from the jitter simulation in time domain. These simulations are made basing on the known jitters models from the literature sources [7,8] and sections of computation programs described below in Section 6. These four kinds of jitter were simulated in Matlab, using mathematic models introduced in subsections above.…”
