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.
