Abstract
A PCM signal demodulating circuit in which a PCM signal corresponding to a code representative of a first sample value obtained by sampling an analog signal with a first sampling frequency is processed to obtain the first sample value, thereby to calculate a pseudo sample value equivalent to a second sample value obtained by sampling the analog signal at a second sampling frequency higher than the first sampling frequency. This is accomplished by passing the PCM signal through a digital filter, a digital-to-analog converter, and a low-pass filter connected in cascade.
