Summary

Description
English: Outputs of bandpass filters centred at 364, 1498 and 4803 Hz (from bottom to top) in response to a segment of a speech signal, the sound “en” in “sense”. The bandwidth of each filter was one ERBN. These filter outputs are similar to the waveforms that would be observed at places on the basilar membrane tuned to 364, 1498 and 4803 Hz. For each centre frequency, the signal can be considered as a slowly-varying envelope (E) imposed on a more rapid temporal fine structure (TFS). The envelope for each band signal is shown by the thick line.
