Abstract

SE CODIFICA UNA SEÑAL DE AUDIO. LA SEÑAL SE DIVIDE PRIMERO EN BANDAS (600) SE SELECCIONA PARA CADA BANDA UN ELEMENTO DE SEÑAL DE NORMA (608), Y SU MAGNITUD CUANTIFICADA SE UTILIZA PARA LAS LISTAS DE UBICACION, LA SEÑAL DESCODIFICADA SE DESCODIFICA POSTERIORMENTE (918, 926) CON MENOS EXACTITUD PARA CUANTIFICAR LOS ELEMENTOS DE SEÑAL SIN NORMA (624).
