Claims (1)

필터, 입력동조, 증폭기, 단간동조, 1차발진기를 포함한 1차믹서와 IF동조단, 2차믹서 등이 직렬계통으로 되는 팔 BG 세캄 L 방식의 공용수신튜너에 있어서, 상기 1차 발진기가 연결된 1차믹서는 다이오드에 의한 더블밸런스드믹서(11)로한 팔 BG 튜너(1)로 되고 상기 믹서(11)의 출력축에 RF 가변트랩기(12), 1차반질기가 변트랩기(13), IF 동조단(14), 증폭기(15)의 직렬계통이 제2믹서(16)와의 사이에 직결된 구성을 특징으로 하는 팔 BG 및 세캄 L 공용튜너의 화면비트발생방지회로.In an eight-channel BG Secam L-type common reception tuner in which a first mixer including an filter, an input tuning, an amplifier, a step tuning, a first oscillator, an IF tuning stage, and a second mixer are connected in series, the first oscillator is connected. The primary mixer is an arm BG tuner (1) made of a double balanced mixer (11) by a diode, and the RF variable trap (12) and the primary half-machine are the trap (13) and the IF on the output shaft of the mixer (11). A screen bit generation prevention circuit of an arm BG and a Secam L common tuner, characterized in that a series system of a tuning stage 14 and an amplifier 15 is directly connected to a second mixer 16. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
