Abstract
A digital system for filtering a single bit input signal according to the transfer function H(z), wherein H(z) has a gain G, a pole at location b , and a zero at location a . The digital system filters the single bit input signal without using computationally expensive multibit multiplication. The digital system achieves these advantages with a digital circuit having a first gain stage generating a gain corrected signal, a delay element generating a delayed gain corrected signal, a feed-forward stage generating a feed-forward signal, and a summer for generating an output signal based upon the sum of the gain corrected signal, the delayed gain corrected signal and the feed-forward signal.
