Abstract: An apparatus for operating a digital signal includes a digital filter, a rounding process unit, a rounding error detecting unit and a rounding error eliminating unit. The allowable input word length is (m) bits for the digital filter. For the input with (n) bits which is longer than the allowable input word length of (m) bits, the rounding process unit processes the rounding and supplies it to the digital filter. The rounding error detecting unit extracts the rounding error based on the (n) bits input signal and the output signal after the rounding process. Utilizing this rounding error detected by the rounding error detecting unit, the rounding error eliminating unit eliminates the rounding error which has been mixed with the filtering output signal of the digital filter.
