Abstract

METODO PARA LA CONVERSION DE UNA SEÑAL ANALOGICA DE AUDIO EN UNA SEÑAL BINARIA Y VICEVERSA, PREVISTO ESPECIFICAMENTE PARA SER UTILIZADO EN UN SISTEMA DE TRANSMISION PARA REGISTRAR Y REPRODUCIR DICHA SEÑAL DE AUDIO SOBRE UN PORTADOR O SOPORTE DE REGISTRO. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE CONVIERTEN MUESTRAS DE LA SEÑAL ANALOGICA DE AUDIO EN PALABRAS DE DATOS DIGITALES DE M BITIOS CADA UNA; SEGUNDA, SE CONVIERTEN DICHAS PALABRAS DE DATOS EN UNA SEÑAL BINARIA; TERCERA, LA SEÑAL BINARIA ES RECONVERTIDA EN UNA SEÑAL DE AUDIO ANALOGICA POR MEDIO DE UN PROCESO DE DESMODULACION, MEDIANTE EL CUAL LA SEÑAL BINARIA ES DESMODULADA Y CONVERTIDA EN PALABRAS DE DATOS DIGITALES DE M BITIOS CADA UNA; Y POR ULTIMO, SE EFECTUA UN PROCESO DE CONVERSION DIGITAL ANALOGICO MEDIANTE EL CUAL DICHAS PALABRAS DE DATOS SE CONVIERTEN EN MUESTRAS ANALOGICAS DE LA SEÑAL DE AUDIO.
