Consider a channel with a 1 MHz capacity and an SNR of63.
a) What is the upper limit to the data ratethat the channel can carry?
b) The result of part a) is the upperlimit. However, as a practical matter, better error performancewill be achieved at a lower data rate. Assume wechoose a data rate of 2/3 teh maximum theoretical limit. Howmany signal levels are needed to achieve this datarate?
