Abstract

ES UN METODO Y APARATO PARA LA BUSQUEDA DE UNA EMISION MULTIVOZ Y UN RECEPTOR DE RADIO, QUE COMPRENDE UN SINTONIZADOR Y DEMULADOR 10 PARA PROCESAR LAS FRECUENCIAS DE RADIO RECIBIDAS DE UNA ANTENA ANT Y LA SALIDA DE LAS SEÑALES DE RADIO DE FM Y SEÑALES DE RADIO NICAM, Y DE UN CODIFICADOR NICAM Y UN CONVERTIDOR D/A 12 PARA LA RECEPCION DE SEÑALES DESDE EL SINTONIZADOR Y DEMULADOR 10, CODIFICADOR Y D/A CONVERSOR DE LAS SEÑALES NICAM, DE MANERA QUE EMITA LA SALIDA SEÑAL PL DE L-CANAL PCM Y UNA SEÑAL PR DE R-CANAL PCM, Y SIMULTANEAMENTE SUMINISTRE EL ESTADO DE EMISION, EL RECONOCIMIENTO DE SEÑALES MC2 Y CTL A UN MICROORDENADOR 14, Y DE ELEMENTOS DE CONMUTACION PRIMARIO Y TERCIARIO PARA LA SELECCION Y SALIDA DE UNA SEÑAL PREDETERMINADA ENTRE LAS SEÑALES DE AUDIO FM, Y LA SEÑAL PL DE L-CANAL PCM Y UNA SEÑAL PR DE R-CANAL PCM, CONTROLADOS POR EL MICROORDENADOR 14, POR LO QUE EL USUARIO PUEDE ESTAR INFORMADO DE LOS IDIOMAS QUE SE EMITEN EN EL SISTEMA DE EMISION ACTUAL. EL METODO DE BUSQUEDA DE MULTIVOCES COMPRENDE LOS PASOS DE COMPROBAR SI LA EMISION RECIBIDA ES UNA EMISION EN MULTIVOCES, ALMACENAMIENTO DE LOS VALORES LOGICOS DEL ESTADO DE LA EMISION, LA BUSQUEDA DE CADA UNO DE LOS IDIOMAS DE LA EMISION EN MULTIVOCES Y DETERMINAR LAS SEÑALES DE CONTROL DE VALORES PREDETERMINADOS, MANTENIENDOLAS POR UN TIEMPO PREDETERMINADO Y EMITIENDO CORRELATIVAMENTE CADA UNA DE LAS EMISIONES EN LOS IDIOMAS DETERMINADOS DURANTE UN TIEMPO DETERMINADO Y DEVOLVIENDO AL ESTADO DE EMISION ORIGINAL ALMACENADO EN MEMORIA.
