Abstract

UN CIRCUITO GENERADOR DE TENSION PARABOLICA INCLUYE UN MONTAJE (IC1) PARA GENERAR UNA CORRIENTE VERTICAL DE DEFLECCION DE DIENTE DE SIERRA (I SUB V) QUE FLUYE EN UNA CURVA DE DEFLECCION VERTICAL (L SUB V), EN UN CAPACITADOR BLOQUEADOR DC (C SUB V) Y UN RESISTOR DE MUESTREO DE LA CORRIENTE DE DEFLECCION (R SUB S). SE ACOPLA UN ELECTRODO EMISOR DE UN TRANSISTOR (Q3) ENTRE LA CURVA DE DEFLECCION Y EL CAPACITADOR. UN ELECTRODO BASE DEL TRANSISTOR SE ACOPLA ENTRE EL CAPACITADOR Y LA RESISTENCIA. UNA CORRIENTE DE COLECTOR (I SUB C) DEL TRANSISTOR VARIA DE UNA MANERA PARABOLICA DE NIVEL VERTICAL Y UN VALOR MEDIO DE DC QUE ES DETERMINADO POR UN VALOR MEDIO DC DE UNA TENSION QUE SE DESARROLLA EN EL CAPACITADOR. LA CORRIENTE DEL COLECTOR SE APLICA A UN CIRCUITO CORRECTOR DE DISTORCION DE RASTREO ESTE -OESTE PARA MODULAR UNA AMPLITUD DE UNA CORRIENTE DE DEFLECCION HORIZONTAL .
