Abstract

AMPLIFICADOR ACTIVADOR DE CINESCOPIO PARA RECEPTORES DE TELEVISION.HJ8SE CARACTERIZA PORQUE EL CATODO (16A) DEL CINESCOPIO ES ACTIVADO POR UN AMPLIFICADOR DE SALIDA DE VIDEO (20, 22) CON UN TRAYECTO DE REALIMENTACION DE CORRIENTE CONTINUA DESDE LA SALIDA A LA ENTRADA DEL AMPLIFICADOR, Y CON UNA IMPEDANCIA DE PERCEPCION (30) INCLUIDA EN EL TRAYECTO DE CONDUCCION DE LA CORRIENTE PRINCIPAL DEL AMPLIFICADOR. LAS VARIACIONES DE CORRIENTE DE CATODO DE NIVEL DE NEGRO SON TRANSMITIDAS A LA IMPEDANCIA DE PERCEPCION A TRAVES DEL TRAYECTO DE REACCION O REALIMENTACION,DE TAL MODO QUE SE DESARROLLE A TRAVES DE LA IMPEDANCIA UNA TENSION REPRESENTATIVA DE TALES VARIACIONES. LA TENSION REPRESENTATIVA ES TRATADA A CONTINUACION PARA DESARROLLAR UNA TENSION DE CONTROL DE POLARIZACION QUE ES UTILIZADA PARA MANTENER UN NIVEL DE CORRIENTE DE NEGRO DE CATODO DESEADO.
