Abstract

PURPOSE: To secure a direct conversion for the sampling frequency of the signal whose pulse duration is modulated into another sampling frequency without returning it to the analog signal.
CONSTITUTION: The several step differences are calculated 11 in sequence in the interpolative polynomial formed by the step differnce which is expressed by the general sum of the products of several step differences and coefficient members and based on PCM signal 10 sampled with the 1st sampling frequency. And the value of several coefficient members in the interpolative polynomial is delivered in sequence according to the clock signal 13 produced by the sampling signal of the PCM signal which is sampled with the 1st sampling frequency. Then these calculated step differences and the coefficient members are multiplied and added each other at arithmetic circuit 15 in order to calculate the value which is expressed by the interpolative polynomial, and PCM signal 17 which is sampled with the 2nd sampling frequency is drawn out approximately.
