Abstract

PURPOSE:To compensate drop-out of the signal rapidly, by using m-number bits and the rest k-number bits out of a prescribed number of bits as information bits and bits for drop-out compensation constituted with bits of the just preceding word respectively. CONSTITUTION:The quantized 10-bit PCM signal and the digital signal where the PCM signal consisting of upper 4 bits from the MSB of the 10-bit PCM signal of the just preceding sampling period is added as bits for drop-out compensation are input to digital signal input terminal 1. When signal drop-out is decided in signal drop-out operation detecting circuit 5, information of bits for drop-out compensation of just preceding word read by memory circuit 6 is supplied to signal drop-out correcting circuit 7, and in this circuit 7, upper 4 bits of the read output signal from memory circuit 4 are substituted with upper 4 bits of information bits of the just preceding word read from memory circuit 6.
