Abstract :
The author states that the method of S.M. Kay and R. Sudhaker (ibid., vol.ASSP-34, p.96-104, Feb. 1986) can be easily modified to provide for (1) invariance of the autocorrelation function to processing and clipping, and (2) spectral estimation by fast Fourier transform of the zero-crossing intervals.<>
