Abstract: An asynchronous, regenerative, digital repeater for use in bipolar digital signalling systems includes an amplifier for receiving and amplifying incoming signals, a first monostable multivibrator for producing regenerated pulses responsively to the output of the amplifier, an output circuit for producing a bipolar pulse train responsively to the output of the multivibrator, and a second multivibrator for inhibiting the first multivibrator for a predetermined interval following the trailing edge of each output pulse to prevent the first multivibrator from responding to the electrical overshoot at the trailing edges of the incoming pulses.
