Abstract
Abstract A pulse generating circuit arrangement comprises a sawtooth generator. The sawtooth generator comprises an adjustable potentiometer connected in series with a capacitor. The input of a potentiometer comprising an adjustable potentiometer connected in series with a voltage divider is connected to the output of the sawtooth generator. The inputs of a threshold switch circuit are connected to the outputs of the potentiometer. The threshold switch circuit comprises a plurality of transistors having emitter electrodes connected to a zero voltage line, base electrodes connected to the outputs of the potentiometer and collector electrodes connected to the corresponding ones of a plurality of outputs and to a source of operating voltage via corresponding ones of a plurality of resistors. The sawtooth generator and potentiometer control the threshold switch circuit to produce at the outputs of said circuit a plurality of output circuits having coincident leading edges and different durations. The adjustable potentiometer of the sawtooth generator controls the duration of the output pulse having a maximum duration provided at one of the outputs of the threshold switch circuit. The adjustable potentiometer of the potentiometer controls the duration of the output pulse having a minimum duration provided at another of the outputs of the threshold switch circuit and the voltage divider of the potentiometer controls the durations of the output pulses having intermediate durations provided at others of the outputs of the threshold switch circuit.
