ABSTRACT:
A signal restoring apparatus in a DVCR, which generates a bit erasure signal by using two threshold value and uses the same in detection of synchronism so that error detection/correction rate in demodulating signals can be improved. The apparatus detects three of "0," "1" and the bit erasure signal by using two threshold having a value different from each other in the signal detection so that matching rate becomes high by using the detected bit erasure signal. When the bit erasure signal occurs over predetermined number, the matching is not performed and the output of the incorrect synchronism signal is restrained by generating the erasure signal, thereby enhancing error correction capability.
