Abstract

Un aparato para descomponer una señal que consta de un número de por lo menos tres canales comprende un analizador (16) para analizar una similitud entre dos canales de una señal de análisis relacionada con la señal que tiene por lo menos dos canales de análisis, donde el analizador está configurado para utilizar una curva de similitud dependiente de la frecuencia previamente calculada como curva de referencia para determinar el resultado del análisis. El procesador de señales (20) procesa la señal de análisis o una señal derivada de la señal de análisis o una señal de la cual se deriva la señal de análisis utilizando el resultado del análisis para obtener una señal descompuesta.
