ABSTRACT:
This invention relates to a deflection arrangement for a video display of color pictures. The arrangement comprises a deflection yoke including a pair of vertical deflection coils toroidally wound on a magnetic core, using a multi-layer terminal technique. An R-C network is coupled between an intermediate terminal of the firstly wound layer of one of the coils and between an intermediate terminal of the firstly wound layer of the other one of the coils. The R-C network suppresses ringing in the coils that are produced by a horizontal deflection coil during horizontal retrace.
