Consider a channel with a 3 MHz capacity and an SNR of 255. a. What is the upper limit to the data rate that the channel can carry? b. The result of part (a) is the upper limit. However, as a practical matter, better error performance will be achieved at a lower data rate. Assume we choose a data rate of 2/3 as the maximum theoretical limit. How many signal levels are needed to achieve this data rate?
