Description
Claims (1)
- 디지탈 디스크에서 재생되는 NRZ변조신호(DIN)를 클럭신호(CLK)에 따라 복조하는 데이타 복조부(10)와, 상기 NRZ변조신호(DIN)의 N비트 채널폭을 계수하는 카운트부(20)와, 상기 카운트부(20)의 출력신호를 상기 NRZ복조신호(SDATA)에 따라 반전구간이 M회 연속반복되는가를 계수하는 반복횟수 계수부(30)와, 상기 카운트부(20)의 출력신호를 1클럭신호(CLK)동안 지연시킨후 상기 반복횟수 계수부(30)의 출력신호와 논리곱하여 동기신호(SYNC)를 출력하는 동기출력부(40)로 구성함을 특징으로 하는 디지탈 디스크 재생장치의 동기 검출회로.
