Abstract
EL PRESENTE DISPOSITIVO COMPRENDE PRINCIPALMENTE UN TRANSFORMADOR QUE UTILIZA UN ALGORITMO DE CONVERSION DE TRES NIVELES DE DECISION, CON VALORES NUMERICOS TERNARIOS B SUB,I}, DONDE B SUB,I} = 1, 0 O -1. ESTE TRANSFORMADOR COMPRENDE UNA FUENTE DE TENSION DE REFERENCIA (V SUB,R}) Y MEDIOS DE CALCULO (MA, MC-A), QUE PERMITEN, EN CADA UNA DE LAS ITERACIONES DE UNA SERIE SUCESIVA DE ITERACIONES DEL ALGORITMO, ESTABLECER UN VALOR DE TENSION FORMADO POR LA SUMA DE UN VALOR OBTENIDO A PARTIR DE LA TENSION CALCULADA EN LA ITERACION ANTERIOR Y UN VALOR QUE ES EL PRODUCTO DEL VALOR TERNARIO OBTENIDO EN LA ITERACION ANTERIOR POR LA TENSION DE REFERENCIA. LOS MEDIOS DE CALCULO COMPRENDEN CAPACIDADES (CR, C1, C2) CONMUTADAS Y CONECTADAS SEGUN UN MONTAJE UNILATERAL, QUE COOPERAN CON UN AMPLIFICADOR OPERATIVO (11) UNICO QUE PROPORCIONA EL VALOR DE TENSION EN CADA UNA DE LAS ITERACIONES. DE APLICACION PRINCIPALMENTE EN AYUDAS AUDITIVAS.
