  • Side pin-cushion distortion correction circuit
    Patent number: 4020390
    Abstract: Side pin-cushion distortion in the display system of a television receiver is corrected by circuitry which includes an "E" core saturable reactor having equal air gaps in a pair of outer legs and an ungapped center leg with a control winding fed by a vertical scan signal source affixed to the central leg and impedance windings fed by a horizontal scan signal source affixed to the outer legs whereby the inductance level of the outer legs is reduced while the change in inductance due to current changes in the control winding remains substantially constant.
