Abstract

PERFECCIONAMIENTOS EN UN CIRCUITO CORRECTOR DEL CONTORNO DEL VIDEO PARA UNA UNIDAD DE REPRESENTACION VISUAL DE VIDEO. EL CIRCUITO CORRECTOR (8) CONSTA DE: UNA BOBINA DEFLECTORA AUXILIAR (5) CON SU EJE PARALELO AL EJE DE LA BOBINA DEFLECTORA (4) DEL TUBO DE RAYOS CATODICOS (9); UN CIRCUITO DIFERENCIADOR (6) PARA DETECTAR LA FORMA DE ONDA DIFERENCIAL PRIMARIA DE UNA SEÑAL DE VIDEO; UN CIRCUITO DE AMPLIFICACION (7) PARA AMPLIFICAR LA SALIDA DE DICHO CIRCUITO DIFERENCIADOR, Y UN CIRCUITO TERMINADOR DE LA CORRECION DE VIDEO (10). LA CORRIENTE DE SALIDA DEL CIRCUITO AMPLIFICADOR (7) ALIMENTA A LA BOBINA DEFLECTORA AUXILIAR (5) SE SUPERPONGA SOBRE EL CAMPO MAGNETICO DE DESVIACION HORIZONTAL.
