Assuming a signal-to-noise ratio of 30 dB, what is the maximum data rate that can be achieved for the dialup bandwidth illustrated in Figure 10.11?
What will be an ideal response?
The bandwidth of the system is 3000 – 600 = 2,400 Hz. Since, S/N is given, we’ll use Shannon’s
capacity expression C = B log 2 (1 + S/N). We should convert 30 dB to real value, which means S/N =
1,000.
So C = 2,400 log 2 (1 + 1,000) = the result to be determined by the reader
