Abstract :
The zero crossing density of a band-limited normal process with a normal power spectrum can be used to determine the process rms frequency. In this correspondence, we give an algorithm for estimating the bandwidth of such a signal from the level crossing density of its envelope. We show that a band-limited normal process can be completely characterized using level crossings.
