Abstract

La presente invencion se refiere a un aparato para presentacion de video que tiene un dispositivo para eliminar la onda de radiacion emitida de un tubo de rayos catodicos. El aparato incluye un alambre blindado enrollado una o varias veces a lo largo de la periferia de una bobina de desmagnetizacion. Los impulsos que tienen el mismo nivel y fase, pero polaridad inversa a aquellos aplicados a un ánodo tubo de rayos catodicos, se aplica al alambre blindado, por medio de lo cual se equilibra la onda radiacion emitida desde el tubo de rayos catodicos.
