Title: Cathode ray tube deflection yoke

Abstract: A cathode ray tube deflection yoke is provided wherein the deflection yokeincludes a plurality of deflection coils. One or more of the deflectioncoils have a non-constant distribution of turns, whereby an electron beampassing through the deflection yoke is deflected by a magnetic field thatvaries according to different numbers of turns relative to position ofelectrons of the electron beam between the entrance and exit of thedeflection yoke. The non-constant turns distribution may be linear ornon-linear, may be monotonic or non-monotonic, and/or may have a positiveor negative turns bias, either in whole or in part. The horizontaldeflection coil and/or the vertical deflection coil, or both, may have anon-constant turns distribution.
