Abstract

PURPOSE: To prevent the generation of a click noise securely by securing error correction and interpolation by holding previously an error detection result in the state showing that pulse-code-modulated PCM data has an error.
CONSTITUTION: Through reading circuit 40, PCM data are read out of memory 10 with error detection results added to headers of respective words and corrections and interpolation are performed by correcting-interpolating circuit 50. At the same time, 1 showing that an error is occurring is previously added as the error detection result to the other output of circuit 40. In this constitution, when any error is not detected by error detecting circuit 20 owing to the disorder in synchronism among frames, etc., 1 showing that the error is occurring is read out of memory 10 as the error detection result and correcting-interpolating circuit 50 decides the occurrence of the error and then performs correction and interpolation. Thus, correction and interpolation are performed securely and the generation of a click noise can be prevented securely.
