Abstract
A burst-mode digital receiver which minimizes any reduction in the minimum input level as compared with a continuous-signal digital receiver includes a unipolar code-to-bipolar code converter for converging unipolar code pulses of an inputted burst signal into bipolar code pulses, an identifying circuit for identifying logic levels of '1' and '0' with an identifying level at a center of a pulse duration of bipolar code pulses outputted from the unipolar code-to-bipolar code converter, and a burst on/off detecting circuit for continuously outputting a signal until the inputted burst signal is finished when a pulse amplitude of the inputted burst signal exceeds a constant value. The burst-mode digital receiver produces an output signal when an AND gate connected to the output terminal of the identifying circuit is turned on at the time the output signal from the burst on/off detecting circuit is turned on.
