Abstract

LOS VALORES DE ENTRADA SE REPRESENTAN DIGITALMENTE (10) Y LOS BITS SE USAN PARA DIRIGIR LAS MEMORIAS (12). SE FORMA UN COMPUESTO (POR EJEMPLO, LA SUMA) DE LAS SALIDAS DE MEMORIA, Y SE USA EL CONTROL DE ACTUALIZACION (13) DURANTE EL "APRENDIZAJE" PARA MODIFICAR LOS CONTENIDOS DE MEMORIA. LA REPRESENTACION DIGITAL SE FORMA MEDIANTE UN CODIFICADOR (14) QUE CODIFICA LOS VALORES DE ENTRADA USANDO UN CODIGO REDUNDANTE, QUE TIENE, PREFERENTEMENTE, UNA RELACION DE DISTANCIA HAMMING A DISTANCIA DE SEÑAL QUE TIENE UNA INCLINACION INICIAL RELATIVAMENTE ESCARPADA Y ESTA MAS CERCA DE SER MONOTONICO DE LO QUE LO ESTA LA RELACION PARA UN CODIGO BINARIO SIMPLE.
