Claims (1)

전압제어발진기와 신호존재 기간과 신호 결락(缺落)기간이 주기적으로 존재하는 입력과 상기 전압제어발진기의 출력을 위상 비교하는 위상비교기와를 가지며, 이 위상비교기의 출력전압이 시정수의 작은 로우패스필터를 통해서 상기 전압제어발진기에 주어지게 하는 것에 있어서 상기 원상비교기의 상기 신호존재기간에 있어서의 출력전압이 시정수가 큰 로우패스필터를 거쳐서 인출되어 상기 위상 비교기의 상기 신호결락기간에 있어서의 출력전압이 삼프링홀드된 것과 레벨비교되어, 그 비교출력전압이 상기 전압제어발진기에 주어지는 PLL회로.It has a voltage controlled oscillator and a phase comparator which phase compares the output of the voltage controlled oscillator with an input having a periodic period of signal presence and a signal missing period, and the output voltage of the phase comparator is a low row of time constant. In giving the voltage-controlled oscillator through a pass filter, the output voltage in the signal existence period of the original comparator is drawn through a low pass filter having a large time constant, and output in the signal loss period of the phase comparator. A PLL circuit in which a voltage is level compared with that of a spring held, and a comparative output voltage is given to the voltage controlled oscillator. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
