<p>In an IIR digital filter, for instance, a multiple-input multiplier and adder circuit is used in place of a plurality of multipliers and a plurality of adders as a structural element. With this structure, since a plurality of multipliers and a plurality of adders are not used, the circuit is designed for miniaturization. In addition, since the multiple-input multiplier and adder circuit makes it possible in structure to carry out pipe-line processing for increasing a processing speed in feedback processing, high speed filter processing is also achievable.</p> |
