Abstract

CIRCUITO ELECTRONICO PARA RECONSTRUIR CANALES DE SOBRECARGA, DE UTILIZACION EN SECCIONES RECEPTORAS DE MODULOS DE INTERFASE TERRESTRE, QUE FORMAN PARTE DE UN SISTEMA DE TRANSMISION VIA SATELITE. CONSTA DE LOS SIGUIENTE ELEMENTOS: UN PRIMER REGISTRO (RS) DONDE SE RECIBEN EN SERIE LOS CODIGOS ADJUDICADOS A UN CANAL DE TRANSMISION DEL SATELITE; UN SEGUNDO REGISTRO (RP) QUE RECIBE EN PARALELO LOS CODIGOS CONTENIDOS EN EL PRIMER REGISTRO; UNA SERIE DE MULTIPLEXADORES (MT1, ... MT6), CON DOS GRUPOS DE OCHO ENTRADAS, CONECTANDOSE A UNO (1,2, ..., 8) LAS SALIDAS DEL SEGUNDO REGISTRO Y AL OTRO (20, 30,..., 90) LOS CODIGOS RELATIVOS A LOS CANALES DE SOBRECARGA.
