Abstract

Un receptor (202) tiene un receptor de conversion descendente (304) para transformar una senal (201) de una primera frecuencia operativa en una segunda frecuencia operativa que es inferior a la primera frecuencia operativa, y un filtro de receptor (308) con estabilizacion del interruptor periodico para filtrar porciones no deseadas de la senal (306) en la segunda frecuencia operativa y para generar una senal filtrada final (203) en la segunda frecuencia operativa.
