Abstract

CIRCUITOS DETECTORES SINCRONOS Y DE SINTONIZACION FINA AUTOMATICA. EL CIRCUITO SE CONFIGURA EN UNA PASTILLA DE CIRCUITO INTEGRADO MONOLITICO, EXCEPTO EL CIRCUITO SINTONIZADO (160, 184). LA SEÑAL DE I.F. SE APLICA A LOS TRANSISTORES (132, 134) PARA SU DEMODULACION SINCRONICA Y A UN CIRCUITO DE SEÑAL DE REFERENCIA (110) PARA LA GENERACION DE UNA SEÑAL DE CONMUTACION. LA SEÑAL I.F. EXCITA A UN AMPLIFICADOR DIFERENCIAL QUE COMPRENDE TRANSISTORES (112, 114), A TRAVES DE CUYOS COLECTORES SE ACOPLA UN PRIMER CIRCUITO SINTONIZADO (160) QUE SE SINTONIZA A LA FRECUENCIA DE LA PORTADORA DE IMAGEN; Y UNOS DIODOS (116, 118) CUYA FUNCION ES LA DE LIMITAR LA SEÑAL DE I.F. EL CIRCUITO SINTONIZADO (160) SE ACOPLA POR MEDIO DE LOS CONDENSADORES (172, 174) A OTRO SEGUNDO CIRCUITO SINTONIZADO (180), QUE COMPRENDE UN CONDENSADOR (182) Y UNA BOBINA (184).
