Abstract

LA LINEAS INTRODUCIDAS EN EL BORDE SUPERIOR DE LA IMAGEN PARA LA MEDICION Y EL AJUSTE AUTOMATICO DE LOS PUNTOS CUT- OFF PARA LOS RAYOS DE ELECTRONES SON MOLESTAMENTE VISIBLES SI LA PANTALLA NO SE ESCRIBE COMPLETAMENTE COMO POR EJEMPLO ES EL CASO DE MONITORES. DURANTE EL TIEMPO DE LA CREACION DE LINEAS DE MEDICION SE DESENFOCAN LOS RAYOS DE ELECTRONES DE MODO QUE ESTOS YA NO SON VISIBLES. MONITORES.
