Abstract
Describes the relationship between the number of frequency sampling filter (FSF) zeros and coefficient quantisation errors implemented in 16-bit fixed-point architecture. An optimal curve for the number to match realistic audiograms and to improve the FSF performance is found and experimental results presented
