Abstract

Un método para detectar el alineamiento en el tiempo de una senal de audio analogico y de una senal de audio digital en un sistema de radio híbrido. El método comprende las etapas de filtrar la senal de audio analogico para producir una senal de audio analogico filtrada, filtrar la senal de audio digital para producir una senal de audio digital filtrada, y emplear la senal de audio analogico filtrada y la senal de audio digital filtrada, y emplear la senal de audio analogico filtrada y la senal de audio digital filtrada para calcular una pluralidad de coeficientes de correlacion, método en el cual los coeficientes de correlacion son representativos del alineamiento en el tiempo entre la senal de audio analogico y la senal de audio digital. También se provee un aparato para llevar a cabo el método.
