2. Suppose that the spectrum of a channel is between 3 MHz and 4 MHz and SNRdB = 24 dB: A. Find the capacity (C) (bps) of the channel. (Hint: use Shannons formula). B. The above capacity is a theoretical limit and is unlikely to be reached. But assume the limit can be achieved. How many signaling levels (L) are required? (Hint: Use Nyquists formula.)
