ABSTRACT:
A dc-coupled packet mode digital data receiver, for use with an optical bus uses peak detectors to adaptively establish an instantaneous logic threshold at the beginning of a data burst. A dc compensator, responsive to outputs of the peak detectors, shunts dc or low frequency currents, corresponding to "dark level" optical signals, from the input of the receiver.
