Abstract

SISTEMAS PARA LA RECEPCION DE SEÑALES DE MENSAJES DIGITALES DE FRECUENCIA MODULADA. CONSISTE EN ABARCAR AUTOMATICAMENTE LAS PERDIDAS DE INFORMACION QUE SURGEN POR DISTORSIONES DE FASE Y AMPLITUD, SEGUN SUS CAUSAS, EN UN DISCRIMINADOR DE FRECUENCIA AL QUE ESTA CONECTADO UN DISPOSITIVO PARA RECONOCER PICOS PERTURBADORES ORIGINADOS POR DISTORSIONES DE REFLEXION, ASI COMO UN CIRCUITO QUE COMPENSA ESTOS PICOS PERTURBADORES Y UN MODULADOR DE AMPLITUD QUE ESTA CONECTADO EN PARALELO A OTRO RAMAL DEL MODULADOR DE FRECUENCIA; LAS SALIDAS DE AMBOS MODULADORES VAN A UN CONMUTADOR QUE SE GOBIERNA POR UN ANALIZADOR DE LA MODULACION DE AMPLITUD.
