Claims (1)

AFT전압검출부(5)에서 임피던스 매칭시킨 AFT신호가 인가되고 동기신호 검출부(10)에서 반전시킨 수평동기 신호가 인가되는 마이콤(IC1)에서는 AFT신호와 수평동기 신호를 비교하여 수평동기 신호가 있을때 튜닝스피드를 빠르게 하고 AFT입 신호가 있을때 상승기간에서 튜닝스피드를 느리게 한후 250ms이내에 AFT다운 신호가 있을때 서어치 튜닝을 멈추도록 하는 자동 서어치 안정화 방법.In the microcomputer IC 1 to which the AFT signal impedance-matched by the AFT voltage detection unit 5 is applied and the horizontal synchronization signal inverted by the synchronization signal detection unit 10 is applied, the AFT signal and the horizontal synchronization signal are compared to each other. Automatic search stabilization method that speeds up tuning speed and stops tuning when there is an AFT down signal within 250ms after slowing down the tuning speed when there is an AFT input signal. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
