ABSTRACT:
An arrangement for regulating the amplitude of a sawtooth generator employs a capacitor which is periodically charged and discharged by a current source by way of a switch, the switch being controlled by a synchronizing signal. The regulating circuit is provided with a second capacitor across which the mean value of the sawtooth pulses present across the first capacitor is formed. The regulating circuit also contains a comparator which compares the mean value with a reference value, and in dependence upon this comparison, the charging current for the first capacitor is controlled in such a manner that the mean value is equal to the reference value.
