Abstract

PURPOSE: To realize a digital compensation according to the request of the reproduced PCM data, by selecting and transferring the PCM data itself or the mean value of the before and after values between the registers in accordance with presence or absence of the compensation detection data.
CONSTITUTION: In case when no compensation is required for the reproduced PCM data transferred up to the register 3, the compensation command data within the compensation bit of the register 4 turns to a low level. And the multiplexer 7 becomes enable via the inverter 8, and thus the PCM data of the register 3 is transferred directly to the register 4 in accordance with the next clock. On the other hand, if the necessity of compensation is detected, the output of the register 3 becomes disabled via the register 4. And at the same time, the mean value between the prevalue PCM data of the register 5 and the postvalue PCM data of the register 1 which are counted by the multiplexer 7 is transferred to the register 4. Thus the reproduced PCM data receives a digital compensation when necessary.
