Abstract
A pulse generator comprises a comparator to the inputs of which are connected a capacitor chargeable by a power source and a voltage divider respectively, two transistors being connected to the output of the comparator, one to set the voltage ratio of the voltage divider and one to provide a discharge path for the capacitor and two additional transistors being selectively connected to the comparator output, one providing a different voltage ratio of the voltage divider and the other providing an independent discharge path for the capacitor.
