Assume that the bandwidth of the voice channel is 2000HZ and the signal-to-noise ratio is 30db. What is the maximum data transmission rate of voice channel?
The maximum achievable data rate is the channel capacity c = BLG (1+s/n)/lg2 = 2000lg (1+1000)/lg2 =19934b/s =19.

Note that the signal-to-noise ratio of 30dB means that the signal-to-noise ratio = 1000.
