Abstract : The patent describes a digital transmission system comprising a transmitter and receiver capable of transmitting and receiving digital data at high bit rates in a noisy environment. It uses transformer coupling to a single transmission line, serial to parallel and parallel to serial conversion, and parity generation and checking circuits. The system is capable of operation from a five volt source and of being densely packaged. The serial digital receiver uses a decoding and filtering circuit which provides high noise immunity for the system. Data transmitted and received is in the form of pulses having a positive and negative peak so as to eliminate the necessity of a separate syne line.
