Higher Order Crossings Spectral Analysis of an Almost Periodic Random Sequence in Noise.

摘要

Under certain conditions the expected numbers of zero crossings observed in both a finite section of a process with a mixed spectrum and in finite sections of its filtered versions determine the frequencies in the discrete spectrum regardless of the magnitude of the 'noise' component.
