SHAVELIS, R., OZOLS, K., 2014. Design of FIR Decimation Filters with Low Group Delay for Audio Applications ” The 14th Biennial Baltic Electronics Conference BEC2014, Tallinn, Estonia, Oct. 6-8
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 minimumphase FIR filters are obtained with decimation factors 16 and 32, respectively. Simulation results and the frequency responses of the minimum-phase filters are provided.
