Methods for estimating the ADC jitter in noncoherent systems

Vadym I. Slyusar, M. Bondarenko


The paper presents the method of estimating the jitter dispersion developed for the case when the clock pulse generator of ADC and the generator of input test signal are not time synchronized. The generalization of the method was carried out for the following cases: input signal represents a sum of harmonic components; ADC system has several channels with equal values of the jitter and additive noise dispersions. The results of numerical simulation are also presented.
