Abstract

Filtro de decimación con razón de decimación seleccionable. Un filtro de decimación para filtrar una corriente de señales eléctricas cuantificadas de procedencia externa con una velocidad determinada que comprende un generador de coeficientes sensible a unconjunto de señales de selección de razón-decimación de procedencia externa para suministar una señal del coeficiente nrmalizado distinta en cada puerto respectivo de una pluralidad de puertos de salida. Un acumulador está acoplado al generador de coeficientes para recibir cada una de las señales de coeficientes normalizados generadas en el mismo. El acumulador recibe la corriente de señales eléctricas cuantificadas para producir, tras el enmascaramiento con las señales eléctricas cuantidicads para producir, tras el enmascaramiento con las señales respectivas de las señales de coeficientes normalizados recibidas, una pluralidad de señales de salida del acumulador. Un detector de desbordamiento de capacidad está acoplado al acumulador paradetectar y corregir cualquier condición de desbordamiento que se produzca en el acumulador.
