Abstract

DISPOSIITVO DE VISUALIZACION DE IMAGEN PARA SEÑALES BINARIAS. SOBRE UN TUBO (3) DEVISUALIZACION DE IMAGEN SE ENCUENTRA UNA UNIDAD DE DEFLEXION (1) A LA QUE LLEGAN DOS SEÑALES, UNA A LA FRECUENCIA DE LINEA Y OTRA A LA FRECUENCIA DE CAMPO; AMBAS PROCEDEN DE UN GENERADOR DE IMPULSOS (9). UN GENERADOR DE SEÑAL (15) APLICA A UN CIRCUITO DE DETECCION PARA TRANSITORIOS VERTICALES; ESTE LO FORMAN UN CIRCUITO DE RETARDO (149) Y UN PUERTA <> EXCLUSIVA (151). LA SALIDA DE ESTA VA, A TRAVES DE UN CIRCUITO DETERMINADOR DE AMPLITUD (153), A UN CONMUTADOR (155) CUYA SALIDA ESTA CONECTADA A UN ELECTRODO DE CONTROL DE TUBO (3). EL CONMUTADOR (155) POSEE UNA ENTRADA ADICIONAL PROCEDENTE DEL GENERADOR DE SEÑAL (15). EL CIRCUITO DE RETARDO (149) ESTA CONTROLADO POR EL GENERADOR DE IMPULSOS (9). LA CIRCUITERIA ENTRE EL GEENERADOR DE SEÑAL (15) Y EL TUBO (3) PUEDE SER VARIABLE. EL DISPOSITIVO REDUCE LA FLUCTUACION VERTICAL DE LA IMAGEN.
