摘要：

The influence of random instabilities in the sampling instants on spectral estimation by the fast Fourier transform (FFT) of harmonic, stochastic processes is considered. The degradation due to the deviation from a uniform sampling is presented by explicit formulas. This degradation, a decrease of the desired signal and an increase of the sidelobe noise, is expressed in terms of the characteristic function of the jitter's distribution.
