Abstract : The invention is a system for transmitting and detecting digital data using logic circuits and operational amplifier techniques from computers. The transmitter extracts stored bits from a shift register and feeds them through logic circuitry to an operational amplifier connected to a tranmission line (or transmitter in a radio link). The logic circuitry causes the amplifier to give OV signals for 'O' data bits and +V signals for 'I' bits. At the other end of the tranmission line (or at a reciever in the radio link), the signals are inverted, +V is added, and the resulting signal is fed into two voltage comparators.
