ABSTRACT:
A circuit arrangement is described for generating a sawtooth current in a cathode ray tube deflection coil. The circuit arrangement has a first and a second multiresonant section. The sections are arranged in series. The cathode ray tube deflection coil is part of the first section. The second section has an inductor. Each section provides a trace period in which the sawtooth current is generated in the cathode ray tube deflection coil and a retrace period in which flyback of the sawtooth current is provided. The circuit arrangement further has a current control circuit coupled to the inductor for controlling the course of the sawtooth current.
