Abstract

PURPOSE:To prevent a detecting mistake of errors, by discriminating a code error in a state of relation under which an output given from each of a syndrome growing circuit, a comparator, an error pointer pattern detecting circuit, etc. is set. CONSTITUTION:The output supplied from a waveform shaping circuit is given to an error detecting circuit 26 via an input terminal 40. A decision signal Ep given from the circuit 26 is supplied to an error pointer pattern detecting circuit 30 via a buffer memory 27 and then a shift register 41 of 7 bits D. Here the output from each of the circuit 30, a syndrome growing circuit 28 and a comparator 45 is supplied to a matrix circuit 47. Then the signal EP is delivered from a correction control circui 48 regardless of the circuit 26 when a prescribed relation is satisfied among those outputs. With such constitution, the detecting mistake of errors can be prevented.
