Abstract
EN LA FIGURA 2 SE MUESTRA UN CIRCUITO PARA LA LINEALIZACION DE UNA SALIDA ANALOGICA-NUMERICA, CON UNA SEÑAL VI ANALOGICA TRANSMITIDA POR UN CIRCUITO DE ENTRADA 10 QUE SE APLICA A UN PUERTO DE ENTRADA DE UN CONVERTIDOR ANALOGICO-NUMERICO 12 CONTROLADO POR UNA SEÑAL DE MUESTRA VS, PARA PROPORCIONAR DATOS NUMERICOS VD EN UN BUS DE DATOS DE BIT N 14. UNA MEMORIA DE LINEALIZACION ANALOGICA-NUMERICA 16 QUE ALMACENA UNA TABLA DE CONSULTA DE VALORES NUMERICOS ESTA ACOPLADA AL BUS 14 PARA RECIBIR DATOS NUMERICOS VD, Y RESPONDER A LOS DATOS NUMERICOS VD PROPORCIONANDO VALORES NUMERICOS LINEALES VERDADEROS DE LA TABLA DE CONSULTA AL SISTEMA DE PROCESAMIENTO DE DATOS NUMERICOS DSP 20 A TRAVES DE UN BUS DE DATOS DE BIT N 18. TEMPORALMENTE, SE ACOPLA UN MICROPROCESADOR 22 ENTRE EL PUERTO DE SALIDA DEL CONVERTIDOR 12 Y EL PUERTO DE ENTRADA DE LA MEMORIA 16 A TRAVES DEL BUS 14, PARA QUE SIRVA COMO UN CONMUTADOR ENTRE EL BUS 14 Y UNA MEMORIA DE PROGRAMACION 24 QUE CONTIENE UNA TABLA DE VALORES NUMERICOS LINEALES VERDADEROS VT. UNA SEÑAL DE COMPROBACION CONOCIDA SE APLICA AL CIRCUITO DE ENTRADA 10, Y LOS VALORES NUMERICOS LINEALES VERDADEROS VT ALMACENADOS EN LA MEMORIA DE PROGRAMACION 24, SE LEEN A CONTINUACION EN LA MEMORIA DE LINEALIZACION 16 PARA PROPORCIONAR UNA RELACION EXACTA Y FIABLE CON UNA CARACTERISTICA IGUAL A LA AMPLITUD DE CADA FASE DE LA SEÑAL DE COMPROBACION CONOCIDA SOBRE EL RANGO COMPLETO DE LA SEÑAL DE COMPROBACION CONOCIDA.
