Abstract

PURPOSE:To obtain a filter with different characteristic by a single circuit by providing a selector to the input of a coefficient multiplier so as to select plural input signals sequentially in the prescribed timing. CONSTITUTION:An input signal is fed respectively to multipliers 6a-6i of each stage and multiplied with prescribed coefficient (ROM 10) and the multiplied value is added by adders 7a-7i via delay means (circuits 8a-8i) sequentially. Selectors 5a-5i are provided to the input side of the multipliers 6a-6i and plural input signals (terminals 1, 2a, 2b) are selected sequentially in a prescribed timing and the coefficient is switched optionally. Thus, a different characteristic is obtained for each input signal thereby forming an excellent digital filter without waste in the operation of an arithmetic circuit or the like.
