ABSTRACT:
The periodicity of a wave structure is determined by detecting a temporal feature such as zero crossings of the wave, measuring time intervals between zero crossings, and developing a histogram of the time intervals. A periodic structure will exhibit a uniformity in the time intervals, whereas a random signal will have random time intervals between zero crossings.
