Abstract

SE RECIBE UNA PORTADORA QUE CONTIENE UNA GRAN VARIEDAD DE SEÑALES DENTRO DE UNA PRIMERA BANDA DE FRECUENCIA, ASI POR EJEMPLO: SEÑALES DE TELEVISION DENTRO DE LA BANDA DE TELEVISION POR CABLE. LAS SEÑALES SE CONVERTIRAN HACIA UNA SEGUNDA BANDA DE FRECUENCIA SITUADA POR ENCIMA DE LA PRIMERA DONDE UNA DE LAS SEÑALES CONVERTIDAS SELECCIONADA RESIDIRA EN UNA FRECUENCIA INTERMEDIA DENTRO DE UNA SEGUNDA BANDA. LA SEÑAL CONVERTIDA SELECCIONADA SE INTRODUCIRA EN UN DETECTOR HOMODINO QUE OPERA EN UNA FRECUENCIA CERCANA O INTERMEDIA. SE PROCESARAN DIGITALMENTE LAS SEÑALES DE SALIDA EN FASE O CUADRATICAS PARA RECUPERAR UNA SEÑAL DE BANDA BASE.
