Abstract
A line scanning circuit supplying a sawtooth current to a deflection coil and producing auxiliary voltages by way of a transformer. The currents through the coil and the windings of the transformer are both switched simultaneously by the same interrupter, but these inductances are separated by diodes and are each associated with an arrangement formed by a diode and a retrace capacitor to supply the current during the line retrace and the beginning of the trace of the scan. The transformer and the coil are fed independently of each other to allow a variation of the scanning amplitude without a change of the E.H.T.
