Abstract
LA INVENCION SE REFIERE A UN RECEPTOR DE SUPERPOSICION, PREFERENTEMENTE PARA UNA RECEPCION DE CANALES MULTIPLE, DE FORMA ESPECIAL PARA LA RECEPCION DE SEÑALES OPTICAS, DONDE SE EFECTUA UNA MEZCLA DE LAS SEÑALES DE RECEPCION CON UNA SEÑAL OSCILATORIA DE UN OSCILADOR EN UNA ETAPA DE MEZCLA PARA LA GENERACION DE UNA FRECUENCIA INTERMEDIA EN UNA ETAPA INTERMEDIA (ETAPA ZF). DE ACUERDO CON ESTE DESCUBRIMIENTO SE PREVE, QUE LA FRECUENCIA (F SUB LO) DEL OSCILADOR SE SINTONICE DISCONTINUAMENTE EN SALTOS (SP 1, SP 2) Y LA ETAPA DE FRECUENCIA INTERMEDIA DE FORMA CONTINUA.
