Abstract

Un aparato para generar una señal de refuerzo de la frecuencia (130), comprende: un generador de señales (200) para generar una señal de refuerzo a partir de una señal de núcleo (120), comprendiendo la señal de refuerzo un intervalo de frecuencias de refuerzo no incluido en la señal de núcleo, en donde una porción de tiempo de la señal de refuerzo comprende señales de subbanda para una pluralidad de subbandas: un banco de filtros de síntesis (300) para generar la señal de frecuencia reforzada (140) mediante la señal de refuerzo (130) , en donde el generador de señales (200) está configurado para llevar a cabo una limitación de la energía a efectos de asegurar que la señal de refuerzo de la frecuencia (140) obtenida mediante el banco de filtros de síntesis (300) es tal que una energía de una banda superior es a lo sumo, igual a una energía en una banda inferior o es superior a una energía de una banda superior, en a lo sumo un umbral predefinido.
