Abstract

The effect of sampling jitter on some periodic signal measurements, namely, the amplitude and phase of a pure sinusoid, is investigated. The parameters are determined by the fast Fourier transform (FFT) algorithm, which is used for manipulating samples in a data-acquisition system. Results are expressed in terms of mean values and variances of the measured parameters. Computer simulation results, based on Gaussian jitter, show the changes of amplitude and phase standard deviations versus the changes of standard deviation of jitter and signal amplitude for different numbers of FFT points
