Abstract

Disposición sintonizadora digital para aparatos receptores de radio-difusión, con un almacenador comprendiendo varios lugares de almacenaje para almacenar frecuencias de recepción y con elementos selectores para la elección de un lugar de almacenaje, en cuyo accionamiento se adopta una palabra de clave almacenada en el lugar de almacenaje elegido en el sistema de sintonización, para la maniobra del proceso de sintonización y con elementos de servicio para la conexión de un alcance de varios alcances de recepción del aparato receptor y con medios para la variación continua de la frecuencia de recepción, caracterizada porque para cada alcance de recepción está previsto un lugar de almacenaje, coordinado al alcance de recepción que, durante el accionamiento del elemento de servicio, que conecta el alcance de recepción, se elige inicialmente y no es elegible por los elementos selectores.
