Abstract

Un método para procesar una señal de difusión de audio digital en un receptor de radio incluye: recibir una señal de difusión de audio digital; desmodular la señal de difusión de audio digital para producir una corriente de audio análogo y una corriente de audio digital; determinar un valor de calidad de señal digital para la corriente de audio digital: mezclar una salida del receptor de radio desde la corriente de audio análogo hasta la corriente de audio digital cuando el valor de calidad de señal digital excede un valor de umbral adaptable de análogo a digital: y mezclar la salida del receptor de radio desde la corriente de audio digital hasta la corriente de audio análogo cuando el valor de calidad de señal digital cae por debajo de un valor de umbral adaptable de digital a análogo, en donde el valor de umbral adaptable de análogo a digital.
