The coverage of TV stations, which is determined by power output, Antenna height, terrain, and frequency, can be extended through use of the which translates the frequency of the signal and amplifies it. This is particularly important in the case of UHF stations whose coverage is more severely limited by such factors as terrain and distance. The use of the translator allows coverage of important ``Holes''...
This paper describes two FM multiplex demodulators which have been designed for systems employing transistorized FM tuners and stereo AF amplifiers. One adapter uses a frequency doubler as a carrier regenerator and employs the sum-and-difference method of restoring the two stereo channels. The other adapter uses a locked oscillator as a carrier regenerator, a time-share detector, and a stereo program...
