Abstract

EN UNOS SISTEMAS AMPLIFICADORES DE CANAL PLURAL SE PROCESAN MUCHAS SEÑALES DE FASE BLOQUEADA DE DIFERENTES FRECUENCIAS ( SOBRE 111-114) COMO UNA SEÑAL COMBINADA ( DESDE 106). ESTAS SEÑALES PUEDEN SER INTRODUCIDAS DENTRO DE UNA CONVERGENCIA DE FASES PROVOCANDO LA APARICION DE ENERGIA MAXIMA EN EL AMPLIFICADOR (109) QUE EXCEDE ENORMEMENTE LOS INDICES DE CAPACIDAD DEL SISTEMA AMPLIFICADOR. PARA ESTO, DE ACUERDO CON LA INVENCION, UN SISTEMA DE AJUSTE DINAMICO MINIMIZA LA ENERGIA MAXIMA PARA LA CUAL EL AMPLIFICADOR (109) SE MANTIENE, AL AJUSTAR ( POR MEDIO DE 131-134) LA RELACION DE FASE RELATIVA DE MUCHAS SEÑALES. EL SISTEMA DE AJUSTE DINAMICO INCLUYE UN DETECTOR DE ENERGIA MAXIMA (153), UN CIRCUITO DE DECISION LOGICO DE CABLE DURO (161) Y UN CONTROL DE DISTRIBUCION (161) PARA CONTROLAR LAS FASES AJUSTE DE EJE (SOBRE 171-174).
