TV link receiver unit realization

In this paper, one practical realization of indoor unit of TV link receiver is described. Receiver unit is part of microwave radio relay system in 10GHz range. Unit is capable for receiving and demodulating FM signals in baseband of up to 10 MHz. Baseband is divided in two parts. First (0 to 5 MHz) is reserved for video signal, and second (5 MHz to 10 MHz) is for two audio subcarriers. Realization is based on satellite receiver in-door unit structure. It include Samsung BS-Tuner, integrated circuit SGS Thompson STV0042 for video processing and microcontroller unit based on Atmel's AT89C2051.
