ABSTRACT:
Each of two terminals transmits a bit stream to a two-wire line in the form of a unipolar pulsed signal, the terminals transmitting pulses of opposite polarity with the bits synchronized, so that the line acts as a distributed exclusive-or gate. In each terminal, pulses on the bus are detected and a consequent received bit stream is exclusively-ored with the bit stream transmitted by this terminal to recover the bit stream transmitted by the other terminal.
