This article describes a data transmission system capable of speeds up to 12 megabits per second using bipolar transmission techniques. Arbitrarily, positive pulses will be used to stand for 1's and negative pulses for 0's. Both the transmitter and the receiver are transformer coupled at their respective ends of the transmission lines for the elimination of the common mode noise and to avoid a common ground loop. The system utilizes the polar RZ format and requires can input clock and an NRZ data signal. At the receiver, the clock signal is extracted from transmitted data and the polar RL signal is decoded.
