Abstract

METODO PARA MODIFICAR UN PRIMER VOCABLO BINARIO QUE COMPRENDE UNA PLURALIDAD DE BITIOS REPRESENTATIVOS DE UNA PRIMERA SEÑAL ANALOGICA, AL OBJETO DE OBTENER UN SEGUNDO VOCABLO BINARIO, CUYOS BITIOS REPRESENTAN UNA SEGUNDA SEÑAL ANALOGICA QUE TIENE UNA RELACION PREFIJADA CON RESPECTO A LA PRIMERA SEÑAL ANALOGICA, Y DISPOSITIVO CORRESPONDIENTE. CONSISTE EN EFECTUAR UNA ATENUACION O AMPLIFICACION EN BASTO, DE PRIMERA APROXIMACION, DESPLAZANDO EL VOCABLO NUMERICO QUE SE VAYA A MODIFICAR Y METIENDOLO EN EL REGISTRO DE DESPLAZAMIENTO, Y EN EFECTUAR UNA AMPLIFICACION EN FINO, O DE MAYOR APROXIMACION, SUMANDO O AÑADIENDO EL VOCABLO SOBREATENUADO POR DESPLAZAMIENTO, CIERTO NUMERO DE VECES, AL VOCABLO ASI DESPLAZADO.
