In an IIR digital filter, for example, a multi-input multiplier/adder circuit is used as a component in place of a plurality of multipliers and a plurality of adders. With this omission of a plurality of multipliers and a plurality of adders, the circuit size can be reduced. Also, since the multi-input multiplier/adder circuit permits pipelining for increasing the processing speed in feedback processing, filter processing can be performed at high speed.
