Abstract :
A transistorized system has been developed for transmitting 2700 voice channels, or 1200 voice channels simultaneously with a TV program. It has the same repeater spacings and the same low noise power as hitherto supplied systems with tube amplifiers. Outstanding details are the underground line amplifiers, the combination of temperature compensation and automatic pilot control of level stabilization, and the equalization of frequency response non-linearity.
