Abstract
The bat E. fuscus is apparently sensitive to the fine structure of the autocorrelation function of its transmitted pulse. This sensitivity supports phase perception in bats at ultrasonic frequencies. An alternative interpretation for the sensitivity to autocorrelation fine structure is explained by a process involving cross correlation of filtered spectrograms. Spectrogram representations are insensitive to a constant phase shift.This publication has 2 references indexed in Scilit:
