Abstract
PURPOSE: To enable the adjustment of a PCM recording and reproducing system to be performed with good accuracy by alarming the information on the extent of production of code errors with audio signal.
CONSTITUTION: The correction signal S1 obtainable in response to the presence or not of any code error in the code error detecting part of a PCM reproducing system is led to an OR gate G1 and monostable multi M. When the signal S1 becomes high level owing to a code error, the multi M is triggered at its rise and its output signal S2 becomes high level during the time τ, when the gate G1 opens and the signal S3 is obtained. The signal S3 and the output S4 of an oscillator O are then supplied to an AND gate G2 and the audio signal of the time τ is obtained as the output S5 of the gate G2. This signal is supplied to a speaker S through a driving circuit A.
