Abstract
Abstract A data signal and a timing signal are combined and transmitted over a single pair of wires to apparatus for separating data signals and timing signals from the combined signal. The apparatus for separating data signals and timing signals from a combined signal has means for differentiating and rectifying the combined signal. The rectified signal applied to a one-shot causes the one-shot to produce a timing signal identical to the original timing signal. The timing signal and the combined signal applied to a flip-flop causes the flip-flop to produce a data signal identical to the original data signal.
