Abstract

Features of digital signals, obtained in the case where the signal sample values are taken at crossings of an original analog signal and a sinusoidal reference function, are discussed. It is shown that spectrum analysis of this kind of nonuniform digital signals, with constant envelope not depending on the signal parameters, might be performed without massive multiplication of multi-digit numbers. Observed aliasing and cross-interference effects are considered and adapting signal processing to the specific signal-dependent sampling nonuniformities is suggested, including adapted spectrum analysis and waveform reconstruction.
