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.
