DIGITAL SIGNAL TRANSMITTING SYSTEM

摘要

In a digital signal transmission system, a predetermined number of words of digital information signals are added bit by bit in a modulo 2 adder to produce a first parity signal. The information signals and the first parity signal are delayed so as to have different delay times to each other, and the signals thus delayed are again added bit by bit in a modulo 2 adder to produce a second parity signal. The predetermined number of words of information signals and the first and second parity signals are Aerially transmitted through a transmission line.
