Abstract

CIRCUITO EXCITADOR QUE CONSTA DE UN PRIMER GENERADOR DE ONDA (20,34,60) Y UN SEGUNDO GENERADOR DE ONDA (22,36,62). CADA UNO (20,34,60;22,36,62) ES CAPAZ DE GENERAR AL MENOS DOS ESTADOS DE VOLTAJE Y EL VOLTAJE INSTANTANEO DE LA PRIMERA ONDA NUNCA ES MENOR QUE EL DE LA SEGUNDA EN UNA CANTIDAD DETERMINADA. EL CIRCUITO CONSTA ADEMAS DE VARIOS ELEMENTOS (24,38) QUE PRODUCEN RESPECTIVAMENTE UNA PLURALIDAD DE ONDAS DE SALIDA CONMUTANDO DE FORMA SELECTIVA A LA PRIMERA O A LA SEGUNDA ONDAS, Y UN DISPOSITIVO DE COMPUERTA (40) PARA CONTROLAR LA CONMUTACION SELECTIVA. EL SISTEMA ES TAL QUE CADA UNO DE LOS ELEMENTOS QUE GENERAN UNA PLURALIDAD DE ONDAS DE SALIDA ES CAPAZ DE GENERAR UNA ONDA DE SALIDA CON AL MENOS CUATRO ESTADOS DE VOLTAJE. EL CIRCUITO EXCITADOR PRODUCE VARIAS SALIDAS APROPIADAS PARA EXCITAR UN DISPOSITIVO VISUALIZADOR DE MATRIZ.
