Abstract
A digital signal processor for recording an analog signal in the form of a PCM signal and/or for reproducing the PCM signal in the form of an analog signal. It has functions of generating a first and a second check code each by performing a modulo 2 operation and of adding a third check code to each of the first and the second check codes for detecting errors. The original signals can thereby be restored completely, even when up to two data sets have been subjected to errors.
