Question 1: What factors affect the transmission of data in the channel? Can the signal-to-noise ratio be arbitrarily increased? What is the significance of Shannon's formula in data communication? What is the difference between bits per second and symbols per second?

Question 2: Assuming that the maximum symbol rate of a channel limited by the Nye's criterion is 20,000 symbols per second, if amplitude modulation is used to divide the amplitude of symbols into 16 different levels for transmission, then the highest data rate that can be obtained (bit/s )how many?

Question 3: Assuming that 64bit/s data (error-free transmission) is to be transmitted over a telephone channel with a bandwidth of 3kHz, how high the signal-to- noise ratio should the channel be? What does this result indicate?
