Twisted Pair Telco Line
A twisted pair telephone line one mile in length is used to carry digital data at a rate Rb bit/s. The line is equalized so that the attenuation is constant at 50 dB over the frequency range 0 Hz to 400 kHz. The phase response of the line is equalized so that it is linear with frequency over this range. Data is transmitted over the line within the bandwidth 0 Hz to 400 kHz. The transmitter and receiver are fitted with ideal RRC filters with ? = 0.4.

a. What is the maximum symbol rate which can be sent over this link?

b. If a binary line code is used, what is the maximum bit rate?

c. What is the maximum bit rate with 4-ASK symbols?
