ABSTRACT:
A variable-gain digital filter includes a selector and multiplier arranged inside the digital filter for regulating gain whereby the number of bits of filter input is X, the number of flip-flops inside the filter is X×n bits, and a (Y×n bit) reduction in the number of flip-flops is enabled. The gain regulation circuit incorporated within the digital filter enables a reduction in circuit scale.
