Assignment:
A transmission line of bandwidth 1200 Hz and of length L = 1000 km, where amplifiers are uniformly placed along the line every 50 km, is employed for data transmission. The modulation format is binary PAM. Let the line be modeled as an ideal channel with constant attenuation of 1 dB/km. Let the amplifiers along the line have gain gA = 50 dB and noise figure FA = 7 dB. Finally, let the noise figure of the receive amplifier be FRc = 5 dB. Determine:
a) The maximum bit rate that guarantees the absence of inter symbol interference.
b) The required transmitted power to guarantee a bit error probability of 10-6.
