Abstract

PARA CONVERTIR SEÑALES DIGITALES EN REPRESENTACION NUMERICA DE COMA FLOTANTE DUAL EN SEÑALES ANALOGICAS, LA ETAPA DE EVALUACION DEL CONVERTIDOR D/A DEBE SER CONMUTABLE PARCIAL O TOTAL EXACTAMENTE EN POTENCIAS DE LA BASE DEL EXPONENTES DE LA CIFRA DE COMA FLOTANTE DUAL. ESTO SOLAMENTE PUEDE GARANTIZARLO UN CIRCUITO DIVISOR AJUSTADO MUY EXACTAMENTE DE LA ETAPA DE EVALUACION. SE TRATA DE CONSEGUIR UNA CONVERSION EXACTA DE UNA SEÑAL DIGITAL EN REPRESENTACION NUMERICA DE COMA FLOTANTE DUAL, EN UNA SEÑAL ANALOGICA. LA MANTISA DE LA CIFRA DE COMA FLOTANTE DUAL SE COMBINA, PREFERENTEMENTE SE MULTIPLICA, CON UN FACTOR DE CORRECCION QUE COMPENSA ERRORES DE TOLERANCIA. SE REALIZA, EN VEZ DEL AJUSTE ANALOGICO DE LAS ETAPAS DE GRADUACION DEL DISPOSITIVO EVALUADOR DEL CONVERTIDOR DE D/A, UN AJUSTE DIGITAL. CONVERSION D/A, AMPLIFICADOR DIGITAL.
