Assignment:
A twisted pair telephone line is equipped with an equalizer that ensures the line has a constant attenuation between 300 Hz and 3300 Hz, and linear phase shift with frequency. A carrier at a frequency of 1800 Hz is modulated with QAM so that digital data can be transmitted on the twisted pair. The transmitter and receiver have ideal RRC filters with roll off factor (r) = 0.5.
a. What is the maximum symbol rate that the twisted pair line can carry without ISI?
b. 256-QAM modulation is used on the link. How many bits are conveyed by each symbol?
c. What is the bit rate on the link?
Provide complete and step by step solution for the question and show calculations and use formulas.
