Estimate of the Average Power of Signals with Fluctuations in the Phases of the Components of Harmonic Oscillations with Aperture Uncertainty of an Analog-to-Digital Converter

Abstract

Results are presented from studies of the estimation of the average power of signals with phase fluctuations of the components of harmonic oscillations. These studies take into account the spectral composition of the signal, as well as the characteristics of the phase fluctuations, along with the aperture uncertainty and sampling frequency of an analog-to-digital converter. Analytic expressions are obtained for the numerical characteristics of the distribution of this estimate for a normal probability distribution of the random quantities with uncorrelated random processes.
