초록

This system exchange half-duplex serial data at 1200 baud by FSK modulating a carrier frequency at 200KHz over the 110V A.C. power line. Transmitter output voltage to A.C. line is 4V p-p and line sensitivity is selected 2.54mV because CISPR Noise limitation is $66dB{\mu}V$ at 150 ${\sim}$ 500KHz. The designed and realized system has abtained system margin of 58 dB and probability of error, Pe = $1.78{\times}10^{-7}$ was obtained
