Abstract

PURPOSE: To reproduce and process PCM signals without malfunction by noise, etc. by controlling the writing and reading of the PCM signals to and from a memory according to the correlations of the plural reference signals of the PCM signal blocks.
CONSTITUTION: The PCM signal block having been reproduced is formed by the series array of the horizontal synchronizing signal Sh, reference signal Sb, PCM video signal, etc. and the signals Sh, Sb are converted to corresponding pulses S101, S102 by the comparators 31, 30 of an operational amplifier, etc. When this pulse 101 is applied to delay circuits 32 thru 34, delay pulses 104, 105 are generated and are processed together with the pulse 102 in a pulse discriminating circuit 36 formed by logic circuits. The circuit 36 generates the detection singal only when the signals Sh, Sb assume the specified correlation. Hence, if the writing and reading of the PCM reproduction signals to and from the memory with the detection sighal of the circuit 36, the PCM signals may be subjecved to reproduction processing without the effect of noise, etc. at the reproducing.
