Consider again the band pass channel illustrated in Figure 12.46. The noise power spectral density is 10-5 and the bandwidth is 10 kHz. Plot the capacity of the channel as a function of signal power P_T, and compute the capacity in the limit as P_T†’ ˆž. Contrast the result of this problem with the result of preceding problem.
