ABSTRACT:
A circuit for horizontal deflection in television picture display devices is described, in which a capacitor for correcting the tangential error by means of an S-shaped distortion of the deflection current is arranged in series with the horizontal deflection coil. This capacitor includes a series arrangement of two sub-capacitors (4, 5) of corresponding capacitance, at least the capacitor (5) which is not directly connected to the horizontal deflection coil (1) having a dielectric which is dependent on the direct voltage, and the junction point (6) of these two capacitors (4, 5) conveys a variable direct voltage.
