Abstract

A deflection yoke is described for use in a cathode ray tube, which has an improved deflection sensitivity. The deflection yoke includes a ferrite core, a vertical coil to generate a vertically defecting magnetic field and a horizontal coil to generated a horizontally deflecting magnetic field. The core has a funnel-shaped body with an opening therethrough defining an inner surface. The horizontal coil includes a pair of saddle-type coils positioned in the core such that at least a portion of the horizontal coil is in contact with the inner surface of the core.
