Abstract
Un codificador de senales de audio de television incluye una matriz que suma una senal de audio del canal izquierdo y una senal de audio del canal derecho para producir una senal de suma. La matriz también resta una de las senales de audio izquierdo y derecha, de la otra, de manera de producir una senal de resta. El codificador también incluye un filtro digital configurable de respuesta infinita de impulso que selectivamente utiliza uno o más conjuntos de coeficientes de filtro para filtrar la senal de resta. Cada conjunto seleccionable de coeficientes de filtro está asociado con una aplicacion de filtrado unica para preparar la senal de resta para la transmision.
