High resolution filtering using low resolution processors










Image Number 2 for United States Patent #5319585.

A high-speed digital filter with a large dynamic range is constructed by operating two low-resolution filters 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 simultaneously, however, the characteristics of both filters are controlled so that one filter performs a coarse level of filtering, while the other filter 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.
