Binary Data Transmission System and Clocking Means

In a binary data transmission system clock pulses are recovered by rectification of the transmitted bipolar pulse signals.

The transmitter generates the bipolar pulse signals by combining a data signal, having positive going pulses for binary one's and ground for binary zero's, with an uninterrupted train of clock pulses, consisting of negative going pulses with respect to ground. The combining means, a resistor circuit, supplies the resulting bipolar signals with positive going pulses for binary one's and negative going pulses for binary zero's for transmission to one or more receivers.

At the receiver the bipolar pulse signal is rectified by two oppositely directed rectifiers, one of which passes the positive signal portions and the other the negative portions. The output of the rectifier for the positive portions corresponds to the original data signal. This signal in inverted form and the output of the rectifier passing the negative portions are fed to an OR circuit to generate the clock pulse train.
