Digital filters in auditory physiology

Menne, D. (1989). Digital filters in auditory physiology. Bioacoustics, Volume 2 (2): 87 -115



In auditory research, the manipulation of signals by filtering with analog electronic filters plays an important role. Recently, digital filters that compute signal modifications in real-time became available. They can mimic all functions of analog filters, and additionally make possible new experimental concepts.

This tutorial paper introduces the concept of digital filters by using analogies from acoustics. Even complex acoustical environments can be simulated with digital filters, as they allow the programming of almost arbitrary frequency and phase responses.
