Abstract
The invention relates to the controlling of picture tubes used in television sets and monitors, more specifically to the linearization of their horizontal sweep. In the system according to the invention, linearization is performed using a linearization coil (L3) equipped with a control winding (L4) and the effective inductance of the linearization coil is adjusted by changing the impedance (Z) that serves as the control winding load.
