ABSTRACT:
An special arrangement of the magnetic components of a horizontal sweep output circuit to reduce the net flux density and magnetic induction that are present at the exterior of a video display. The special arrangement meets the new, lower VLF electro-magnetic emission standards of some of the European countries, such as Sweden. The method used for obtaining this special arrangement of horizontal sweep output components is also disclosed.
