Signal recovery from nonuniform samples and spectral analysis on random nonuniform samples
Farokh Marvasti · 2005
The power spectrum of a signal derived by random nonuniform sampling of an analog signal (random or deterministic) is analyzed in terms of the power spectrum of the analog signal. It is shown that the spectrum consists of the original signal with a background white noise. The same analysis holds for uniform samples with time jitter and PAM with some missing samples. We show finally that the power spectrum of random pulse sequence is proportional to the power spectrum of the pulse.
