Claims (1)

헤드를 통하여 인가되는 상태 신호에서 동기 신호를 검파시켜 1클럭 지연형 플립플롭을 통하여 카운터가 리셋트되도록 하고 클럭에 따라 카운터를 계수시켜 동기신호 인가시를 감지하도록 하여 검파 및 카운터되는 상태 신호가 일치될 때에 동기 신호로서 출력되게 한 디지탈 오디오 기기의 동기 검출방법.The synchronization signal is detected from the status signal applied through the head, and the counter is reset through a one-clock delay flip-flop. A synchronization detection method of a digital audio device, which is output as a synchronization signal when a signal is generated. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
