Author
Wiederspahn, W. H.
Title
A coaxial carrier-communications system
Publisher
Monterey, California. U.S. Naval Postgraduate School
Description

This work constitutes a survey investigation of the LI carrier system employed by the Bell Telephone Company for transmission of telephone messages. Although the system is being used experimentally for television transmission no comprehensive program of commercial application is presently being carried out; such a program should materialize in the very near future. For this reason emphasis has been placed on the voice transmission aspects of the system. It should be evident however that minor changes in equipment will also provide for a wide band television transmission.
