Abstract
The saddle windings of the vertical deflection coils 31, 32 of a CRT are provided with external lines 11, 12 which establish distributed capacitances with the turns of the windings. Such lines present low impedance flow paths for unbalanced ringing currents induced in the vertical deflection coils by a high frequency horizontal deflection field, thus damping/dissipating the ringing currents and preventing their distortion of the displayed image.
