Design of FIR decimation filters with low group delay for audio applications

Rolands Shavelis, Kaspars Ozols

Abstract

In this paper a design of FIR decimation filters with low group delay (less than 1 millisecond) is investigated. Given an input sampling rate of 192 kHz, linear-phase and minimum-phase FIR filters are obtained with decimation factors 16 and 32, respectively. Simulation results and the frequency responses of the minimum-phase filters are provided.
