Abstract
A digital filter with integrated decimation shapes a sampled signal and reduces its sampling rate. The filter includes, in cascade, a prefilter (5), a decimator stage (8) and an equalizer (9). The prefilter is a simplified FIR filter in which only logical operations are performed; all multi-digit multiplications are performed only in the equalizer, at the reduced sampling rate. This results in a filter having increased throughput and/or occupying a reduced area.
