ABSTRACT:
A system and method for providing a dc accurate multi-rate digital filter with common coefficient set and dc gain correction utilizes at least one common coefficient set and at least one dc gain correction factor to provide a variable, dc accurate and corrected, multi-rate, digital filter using dc gain corrected subsets of the one stored common coefficient set. The filter maintains at least one common digital filter coefficient set which includes a number of coefficient values.
