FILTER PROCESSING INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To reduce the amount of control data to be inputted to change filter characteristics to less than the amount of data of a filter coefficient. SOLUTION: A filter processing integrated circuit comprises: a storage circuit; a filter coefficient calculating unit which receives frequency information specifying a passing band of an output signal in filter processing and sets a filter coefficient calculated based upon the frequency information in a storage circuit; and a filter unit which performs the filter processing for an input signal based upon the filter coefficient set in the storage circuit and outputs the output signal.
