Abstract

본 고안은 안테나에서 유기된 신호를 증폭하는 부스터와, 상기 부스터에서 출력된 고주파신호를 중간주파수 검파부에서 출력되는 자동이득 제어신호에 따라 증폭하도록 자동이득 조절기능이 내장된 증폭부와, 상기 증폭부에서 출력된 고주파신호중에서 희망하는 채널신호를 선국하여 상기 증폭부에 자동이득 제어신호를 공급하는 중간주파 검파부에 공급하는 튜너부로 구성되어 안테나에 유기된 신호의 전계에 따라 튜너에 입력되는 신호의 레벨을 조절함으로써 선명한 화질과 음질을 제공하는 튜너의 입력레벨 조절회로에 관한 것이다.The present invention is a booster for amplifying the signal emitted from the antenna, an amplification unit with a built-in automatic gain control function to amplify the high frequency signal output from the booster according to the automatic gain control signal output from the intermediate frequency detector, and the amplification A tuner section for tuning a desired channel signal among the high frequency signals outputted from the section and supplying an automatic gain control signal to the amplification section, and a tuner section for supplying the signal to the tuner according to the electric field of the signal induced by the antenna. The present invention relates to an input level control circuit of a tuner that provides a clear picture quality and sound quality by adjusting the level of.
