Abstract

PURPOSE: Influences of noises can be eliminated without providing shields, filters, and the like, by the use of a pulse signal that is synchronized with sampling frequencies and the like as a switching control signal.
CONSTITUTION: A sampling signal is generated by a sampling frequency generator 1 which supplies a sampling signal and a clock signal to various portions of a PCM accoustic device. The sampling signal is input to a switching regulator 2, and is employed as a switching control signal. Since the ripples and induced noises con- tained in the output of the switching regulator have the same frequency as the sampling signal, these noises can be eliminated by a filter that is provided to eliminate the influence of the sampling frequency.
