A new electronic telegraph regenerative repeater

THE GROWING use of teletypewriter service has brought about an increasing need for regeneration. Operating speeds have tended to become higher; more multibranched long-haul circuits are being used, and it has become desirable to allow greater latitude in the maintenance of receivers and other apparatus. These factors cause an increase of signal distortion along the transmission path and a loss of tolerance to distortion at the receiving end of the path. Where the signal distortion is excessive, a regenerative repeater (or even several regenerative repeaters) connected along the circuit may be the best economic answer, and is frequently the only answer to the problem.
