Abstract

In order to cause scan and/or fly-back voltages (Vsca, Vfly) supplied by a horizontal output stage (1) to vary at a desired rate during a change of state in a horizontal deflection circuit (1, 2, 4), a feedback circuit (4) is provided. This feedback circuit (4) processes the scan and/or fly-back voltages (Vsca, Vfly) to a control voltage (Vco) with which a duty cycle (dc) of a drive signal (Hdr) of a switching element (Tr) in the horizontal output stage (1) is influenced.
