Abstract
La presente invencion se refiere a un circuito para eliminar ruido de campo eléctrico de radiacion en un aparato de vídeo que puede compensar por completo el ruido del campo eléctrico de radiacion generado en la cara frontal del CRT al ajustar de manera variable y aplicar la señal de forma de onda, la amplitud y la fase de la cual son opuestas a aquellas del ruido de campo eléctrico de radiacion formado en la cara frontal del CRT. El circuito para eliminar el ruido del campo eléctrico de radiacion conforme a la presente invencion incluye una seccion de compensacion undulatoria de alto voltaje que incluye un nucleo cilíndrico, en donde un cable guía de alto voltaje del FBT pasa a través del nucleo cilíndrico, para eliminar un componente undulatorio del alto voltaje aplicado al ánodo del CRT conforme a la señal de pulso de polaridad negativa desde la bobina de induccion del FBT, y una seccion de compensacion del ruido de campo eléctrico de radiacion generado desde la cara frontal del CRT mediante la aplicacion de la señal de pulso de polaridad negativa a la periferia del CRT.
