Abstract
CIRCUITO DE DEFLEXION DE UN APARATO DE PRESENTACION DE IMAGENES DE VIDEO. COMPRENDE UN AMPLIFICADOR VERTICAL (53) DEL CIRCUITO (100) DE DEFLEXION VERTICAL CON UN TRANSISTOR (Q1) DE SALIDA QUE FUNCIONA COMO CONMUTADOR CONDUCTOR QUE ACOPLA UNA TENSION DE ALIMENTACION AMPLIFICADA (EN EL TERMINAL 3) A UN DEVANADO (LV) DE DEFLEXION VERTICAL. UNA RED DE REALIMENTACION (R7, R8, C4) ESTA ACOPLADA ENTRE UN TERMINAL DE SALIDA (PATILLA 5) Y UN TERMINAL DE ENTRADA (PATILLA 1) DEL AMPLIFICADOR PARA PROPORCIONAR UN AVANCE DE FASE. UN DIODO (D1) INFLADOR DE NIVEL ESTA ACOPLADO A LA RED DE REALIMENTACION. EL DIODO FIJADOR DE NIVEL REDUCE LA MAGNITUD DE UNA SEÑAL DE REALIMENTACION PARA RETARDAR EL INSTANTE EN QUE EL TRANSISTOR DE SALIDA EMPIEZA A FUNCIONAR COMO ETAPA AMPLIFICADORA. SE REDUCE ASI EL ALARGAMIENTO DEL RETORNO DE TRAZA VERTICAL DEBIDO A LA SEÑAL DE REALIMENTACION.
