TWO previous papers before the American Institute of Electrical Engineers discussed the activities of the Bell System in the development of multiplex telephone and telegraph systems using carrier c
The system provides up to 19 high-quality full duplex teleprinter circuits, within the range 300-2750 c/s, over physical, carrier, or radio links.
The system, called ZIG, was developed in Germany to operate on a two-wire transmission line to which the locomotive stations are coupled inductively via loop aerials.
This system was inaugurated on September 10, 1925, between Sydney and Melbourne, 450 miles apart.
T HE use of power from hydro-electric generating stations and central steam plants has increased until single companies serve a territory of many thousands of square miles and the problem of coordi

Seven telephone channels and one telegraph channel on one single-conductor deep-sea cable have been made possible by t h e employment of carrier current on one of the two submarine cables across Ca
The submarine telephone cable system between the Australian Mainland and the island State of Tasmania is described.
We investigate coupling mechanisms between the amplitude and the carrier-envelope offset phase in mode-locked lasers.
We stabilized the carrier-envelope phase of the pulses emitted by a femtosecond mode-locked Laser by using the powerful tools of frequency-domain laser stabilization.
