Abstract :
The paper describes a new multiplexing system employing time division. The system features pulse amplitude modulation with a filtering arrangement for minimizing the required transmission bandwidth. The distortion and crosstalk requirements for commercial applications are met over transmission paths including radio relay repeaters. A discussion of the channelizing, synchronizing, transmission equipment, and system performance data is included.
