WebbIn the case of no bandwidth limitation, it can be shown that the channel capacity approaches a limiting value C ∞ given by C ∞ = lim W →∞ Cc = S n0 loge2 = 1.44 S n0 (32.3) The channel capacity variation with bandwidth is shown in Figure 32.3. Figure 32.3 Channel capacity variation with bandwidth. 32.2 WebbNote that the value of S/N = 100 is equivalent to the SNR of 20 dB. If the requirement is to transmit at 5 mbit/s, and a bandwidth of 1 MHz is used, then the minimum S/N required is given by 5000 = 1000 log 2 (1+S/N) so C/B = 5 then S/N = 2 5 −1 = 31, corresponding to an SNR of 14.91 dB (10 x log 10 (31)).
