摘要:
The present invention relates to a method for correction of the horizontal scanning current of a cathode-ray tube based on a modulation of this scanning current by a substantially parabolic signal at the image frame frequency, obtained by a squaring of a current ramp, including inflecting the ends of this current ramp before its squaring.
