Abstract

UNA ONDA DE VOZ DE ENTRADA RECORTADA SE DIVIDE (3) EN DIFERENTES SERIES DE SEÑALES POR MEDIO DE UNA TRANSFORMADA DE UN TREN DE ONDAS TAL COMO DE DAUBECHIES, QUE A CONTINUACION SE ESCALAN O SE PROCESAN DE OTRA FORMA (4) PARA REDUCIR LOS EFECTOS DEL RECORTE, ANTES DE RECONSTRUIR (5) LA ONDA DE VOZ UTILIZANDO LA TRANSFORMADA INVERSA.
