摘要
Geometrical correction adapted for colour television tubes. The means of correction comprises two symmetrically disposed magnetic cores (34, 35) carrying coils (37, 38) traversed by currents related to the line or frame deflection currents depending on whether the correction is performed on the line or the frame.
