ABSTRACT:
Herein disclosed is a digital filter coefficient setting apparatus which can search and select a specified filter coefficient element corresponding to a specified coefficient parameter inputted by a parameter inputting unit from among the plurality of filter coefficient elements stored in a coefficient storing unit and calculate a specified filter coefficient element on the basis of the specified coefficient parameter when the specified filter coefficient element is not selected from among the plurality of filter coefficient elements stored in the coefficient storing unit, thereby enabling to efficiently set a digital filter in response to a specified filter coefficient element corresponding to any possible specified coefficient parameter inputted therein, as well as to reduce a time required for obtaining the specified filter coefficient element.
