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.
Claims6
A deflection yoke for producing electron beam scanning in a cathod ray tube of a video display, comprising:
- a core made of a permeable magnetic material;
- a toroidal, first vertical deflection coil cooperating with said core for producing a vertical deflection field, said first vertical deflection coil having a plurality of winding layers wound around said core in a multiple layer winding technique;
- a horizontal deflection coil for producing a horizontal deflection field;
- and
- a ringing suppressing impedance coupled to an intermediate terminal between end winding turns of a winding layer of said first vertical that is remote from a center winding layer of said first vertical deflection coil for suppressing ringings that are produced in said first vertical deflection coil by said horizontal deflection field.
