Telephone channels have a bandwidth of about 3.1 kHz. Answer the following questions. a) If a telephone channel's signal-to-noise ratio (SNR) is 2,000 (the signal strength is 2,000 times as much as the noise strength), use the Shannon Equation to calculate the maximum data rate of a telephone channel? b) How fast could a telephone channel transmit data if the SNR were increased massively, from 2,000 to 20,000? (Note: This would not be realistic in practice.) c) With an SNR of 2,000, how fast could a telephone channel transmit data if the bandwidth were increased to 4 kHz? Show your work or no credit. d) What can you conclude from these calculations
