Abstract

EN UNA DISPOSICION DE CONEXION PARA DECODIFICAR UNA SEÑAL MULTIPLE EN UN RECEPTOR DE RADIODIFUSION ESTEREO, POR LO QUE SEÑAL MULTIPLEX CONTIENE UNA SEÑAL SUMA (L+R) EN LA BANDA BASE, UN PORTADOR AUXILIAR MODULADO CON UNA SEÑAL (L-R) DIFERENCIA Y UNA SEÑAL PILOTO CON LA SEMIFRECUENCIA DEL PORTADOR AUXILIAR, SE MULTIPLICA LA SEÑAL MULTIPLEX EN FORMA DIGITAL CON UN SOPORTE DE REFERENCIA OBTENIDO DE UNA CADENCIA DE EXPLOSION PRODUCIDA EN EL RECEPTOR DE RADIODIFUSION EN DOS POSICIONES DE FASE DESPLAZADAS ENTRE SI ALREDEDOR DE 90 . LAS SEÑALES MEZCLA PRODUCIDAS A TRAVES DE MULTIPLICACION SE MULTIPLICAN CON SEÑALES DE CORRECCION MEDIANTE FORMACION DE SEÑALES MEZCLAS CORREGIDAS. LAS SEÑALES DE MEZCLA CORREGIDA SE ADICIONAN Y JUNTAMENTE CON LA SUMA SE REALIZA UNA CONEXION MATRIZ PARA LA FORMACION DE SEÑALES (L, R) AUDIO-ESTEREO.
