<p>PURPOSE:To reduce the correction error by replacing a data with a just preceding value with highest correlation at correction disable state and applying succeeding decoding with the replaced decoding value. CONSTITUTION:The decoder consists of an input terminal 42 for transmission data, an error detection correction circuit 44, an inverse quantizer 46, an adder 48, a switch 50 switched by a correction disable error code, a D flip-flop 52 acting like a delay device for one sample interval, and an output terminal 54 for the decoded value. Then the decoded value corresponding to the coded code disabled of error correction is replaced with the decoding value at one preceding sample with the highest correlation and the succeeding sample is decoded according to the replaced decoding value. Then the correction error is reduced.</p> |
