Abstract

EN UN DEMODULADOR PARA SEÑALES DE DATOS, CUYA TRANSMISION DE REALIZA A TRAVES DE TRANSFORMACION DE EXPLORACION DE FASE DE UN SOPORTE AUXILIAR BAJO PRESION, DONDE UNA SEÑAL MULTIPLEX QUE CONTIENE LA SEÑAL DE FRECUENCIA SOPORTE AUXILIAR SE CONDUCE A TRAVES DE UN FILTRO PASABANDA Y UN LIMITADOR DE AMPLITUD, SE TRANSFORMA LA SEÑAL DE FRECUENCIA PORTADORA LIMITADA DE AMPLITUD, EVENTUALMENTE BAJO OTRA FILTRACION, EN VALORES DE EXPLORACION DIGITAL, QUE SON GUIABLES POR MEDIO DE UN LAZO DE REGULACION DE FASE PARA LA DERIVACION DE UNA SEÑAL DE INTERVALO DE BIT.
