<p>A high-speed digital filter with a large dynamic range is constructed by operating two low-resolution filters (545,548) in parallel, which is referred to as an "overlap" mode of operation. In this overlap mode of operation, both low-resolution adaptive filters operate on the input data (an) simultaneously, but the characteristics of both filters are controlled so that one filter (545) performs a coarse level of filtering, while the other filter (548) performs a finer level of filtering and also removes any errors introduced by the first filter. Some application examples include echo canceling, equalization, and deghosting filters. <IMAGE></p> |
