Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE SINCRONIZACION DE EMISORES (30) EN UNA RED DE DIFUSION, PARTICULARMENTE UNA RED DE DIFUSION, QUE INCLUYE UN PUESTO DE PRODUCCION (10) DE UN PROGRAMA CONECTADO POR ENLACES DE TRANSMISION (10) A DICHA PLURALIDAD DE EMISORES ALEJADOS DEL LUGAR DE PRODUCCION, TRANSMITIENDO EL LUGAR DE PRODUCCION A CADA EMISOR UNA SEÑAL FUENTE DE BANDA BAJA QUE CORRESPONDE AL PROGRAMA Y CADA EMISOR DIFUNDE UNA SEÑAL FINAL EN MODULACION DE FRECUENCIA DE LA MISMA PORTADORA SINUSOIDAL SEGUIDA DE UNA PLURALIDAD DE ETAPAS DE TRATAMIENTO DE LA SEÑAL FUENTE. EL PROBLEMA QUE PRETENDE RESOLVER LA INVENCION ES EL DE LA INTERFERENCIA MUTUA DE EMISORES VECINOS, ESPECIALMENTE EN LAS ZONAS DE RECUBRIMIENTO DE EMISION (35). EL PROCEDIMIENTO SEGUN LA INVENCION SE CARACTERIZA PORQUE: CONVIERTE LA SEÑAL FUENTE EN FORMA NUMERICA POR ESCALONAMIENTO A UNA FRECUENCIA DE ESCALA DETERMINADA PARA TRANSMITIR UNA SEÑAL FUENTE NUMERADA A DICHOS EMISORES, EN EL QUE DICHAS ETAPAS DE TRATAMIENTO DE SEÑAL FUENTE NUMERADA SE SINCRONIZAN EN DICHA FRECUENCIA DE ESCALAS Y PORQUE EN UNA DE LAS ETAPAS DE TRATAMIENTO DE LA SEÑAL FUENTE, SE APLICA UN RETARDO PREDETERMINADO EN LA DIFUSION DE LA SEÑAL FINAL.
