Abstract :
Within the last decade, the use of the negative impedance type of repeater in the telephone plant has proved to be a very satisfactory device to improve transmission on circuits up to about 25 miles in length. This type of repeater is both simple and low in initial cost, and when properly installed, its operating and maintenenace cost is practically negligible.
