ABSTRACT:
An improved digital filter capable of advantageously completing a filter operation through a convolution using a filter coefficient used in each stage of multi-stage digital filters and previously stored in a ROM, which includes a control unit for outputting a control signal; an input buffer for buffering a data inputted in accordance with the control signal and for outputting the buffered data; a data storing unit for storing a data outputted from the input buffer in accordance with a control signal applied thereto; a ROM for storing a filter coefficient obtained through an operation of the filter coefficient of a multi-stage; an addressing unit for addressing an address of the filter coefficient stored in the ROM; and a multiplying and accumulating unit for convoluting the data outputted from the data storing unit and the ROM.
