Claims (1)
- 알디에스의 동일 프로그램 방송 튜닝에 있어서, RDS 및 PLL 제어부(6)가 튜닝시마다 중간주파증폭 및 검출부(2)로 입력되는 중간주파레벨미터신호(ILM)의 레벨을 자체 램에 저장하고, AF 리스트 조사를 마친후, 최고 높은 중간주파레벨미터신호(ILM)를 갖는 주파수를 PLL의 기준 주파수(RF)로 선택하여 동조하게 하되, AF 리스트상의 주파수를 미리 인식하여 PLL상의 기준주파수(RF)가 변환되기전에 에러신호를 튜너(1)에 일정시간(PU)동안 출력하여 그 튜너(1)의 동조를 제어하는 것을 특징으로 하는 RDS AF 고속처리 방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
