Abstract

FILTRO DE DECIMACION QUE USA UN CIRCUITO DE RELLENO CON CEROS PARA SUMINISTRAR UNA RAZON DE DECIMACION SELECCIONABLE. UN FILTRO DE DECIMACION PARA FILTRAR UNA CORRIENTE DE SEÑALES ELECTRICAS CUANTIFICADAS DE PROCEDENCIA EXTERNA QUE COMPRENDE UN GENERADOR DE COEFICIENTES SENSIBLE A UN CONJUNTO DE SEÑALES DE SELECCION DE RAZON-DECIMACION DE PROCEDENCIA EXTERNA PARA SUMINISTRAR UNA SEÑAL DEL COEFICIENTE NORMALIZADO DISTINTA EN CADA PUERTO RESPECTIVO DE UNA PLURALIDAD DE PUERTOS DE SALIDA. EL GENERADOR DE COEFICIENTES EMPLEA UN CIRCUITO DE RELLENO CON CEROS PARA SUMINISTRAR LAS SEÑALES DE COEFICIENTES NORMALIZADOS. UN ACUMULADOR ESTA 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 ELECTRICAS CUANTIFICADAS PRODUCIENDO UNA PLURALIDAD DE SEÑALES DE SALIDA DEL ACUMULADOR. UN DETECTOR DE DESBORDAMIENTO DE CAPACIDAD ESTA ACOPLADO AL ACUMULADOR PARA DETECTAR Y CORREGIR CUALQUIERCONDICION DE DESBORDAMIENTO QUE SE PRODUZCA EN EL ACUMULADOR.
