  • System and method for transmission of information
    Patent number: 4184045
    Abstract: Serial transmission of binary information on a two-conductor line is effected by transmitting a periodic signal on one conductor and earthing the other conductor when a binary "0" is to be transmitted, while the periodic signal is transmitted on the other conductor and the first conductor is earthed when a binary "1" is to be transmitted. The sum of the signals transmitted via the two conductors is established for controlling the recovery of the binary information from the difference between the signals transmitted on the two conductors. On the transmitter side, use is made of a switch controlled by the binary information, for connecting the periodic signal to either of the two conductors and, on the receiver side, use is made of a correlator or a signal-adapted filter for recovering the transmitted information.
