Abstract

DISPOSICION DE CIRCUITO PARA LA RECEPCION DE DOS SEÑALES DE MODULACION EN TELEVISION. AMBAS SEÑALES DE MODULACION SON TRANSMITIDAS EN DOS PORTADORAS ESPECIFICAS. UNA DE ELLAS PUEDE SER LA SUMA DE SEÑALES DE ESTEREOFONIA O UNA PRIMERA SEÑAL DE SONIDO, Y LA SEGUNDA PUEDE SER LA SEÑAL DEL CANAL DERECHO O UNA SEGUNDA SEÑAL DE SONIDO. PARA LA RECEPCION ESTEREOFONICA, LA SEÑAL DEL CANAL IZQUIERDO SE FORMA A PARTIR DE AMBAS SEÑALES DE MODULACION MEDIANTE UNA ETAPA DE ADICION O DE SUSTRACCION. LA GANANCIA PARA LA SEÑAL DE SUMA ES MAYOR, EN UNA FACTOR DE DOS, QUE LA GANANCIA PARA LA SEÑAL DEL CANAL DERECHO. CUANDO SE RECIBEN DOS SEÑALES DE SONIDO, LA GANANCIA PARA LAS DOS SEÑALES DE MODULACION ES LA MISMA. LAS FRECUENCIAS DE LAS DOS PORTADORAS ESTAN SITUADAS MUY PROXIMAS ENTRE SI.
