Abstract

The pulse distributor takes pulses from a single pulse source and establishes pulses on each one of a plurality of output conductors, sequentially. The circuit dispenses with the need for a D.C. bias source for control purposes in each stage.

Pulse Distributor

The pulse distributor takes pulses from a single pulse source and establishes pulses on each one of a plurality of output conductors, sequentially. The circuit dispenses with the need for a D.C. bias source for control purposes in each stage.

The distributor is composed of four identical stages which respond to clock pulses and provide an output pulse from each stage, sequentially. Each stage comprises a condenser C which, when charged, inhibits operation of the respective stage. When the condenser C1 of the first stage is discharged, this stage 1 is enabled to pass the next clock pulse upon supply of which transistor T1 becomes conductive and condenser C1 is charged. The charging current generates an output pulse from this stage 1 via transformer Q1. The output pulse is also applied to a delay circuit D1 from which the delayed pulse emerges after termination of the clock pulse. The delayed pulse is applied to the base of transistor T2 of stage 2 to the effect that this transistor becomes conductive and the condenser C2 is discharged. Now, stage 2 is enabled to pass the next clock pulse. The passage of the clock pulse through any stage charges the condenser of that stage and then operates to discharge the condenser of the next stage. The holding circuit, which allows the distributor to be stopped at any stage, then proceed later, can be incorporated between any two succeeding stages.
