A pulse supply system of the type having parallel-operating, like constructed pulse generating units is described. One unit functions as the active unit, while the other is a reserve unit with the posibility of switching between these states. Each of the duplicate pulse generators contains one stage of a bistable circuit, at the output of which is available an unambiguous signal indicative of the state of each pulse generator. A signal emitter is available in each pulse generating unit for producing an output indicative of the state of the applicable pulse generating unit; the signal emitters being conditioned by the bistable circuit. An evaluation circuit for each output pulse phase is present in the circuit receiving the pulses; this circuit receives both the signal emitter outputs and the pulse supply outputs. The evaluation circuit forwards only the pulse from the generator indicated as being in the active state. |
