Abstract

Un método de reducir las componentes de interferencia en una señal modulada en frecuencia, que comprende una señal portadora que está modulada en frecuencia, por al menos una señal moduladora de frecuencia fija, caracterizado porque la señal portadora es modulada en anchura de impulsos por la componente de primer orden de banda lateral inferior que está contenida en la señal modulada en frecuencia como resultado de la señal moduladora.
