If the channel is band limited to 6 kHz and signal to noise ratio is 16, what would be the capacity of channel?
Correct Answer: D
Question 20 Explanation:
→ Shannon Capacity (Noisy Channel) In presence of Gaussian band-limited white noise, Shannon-Hartley theorem gives the maximum data rate capacity.
C=B log 2 (1+S/N).
where S and N are the signal and noise power, respectively, at the output of the channel.
→ This theorem gives an upper bound of the data rate which can be reliably transmitted over a thermal-noise limited channel.
=6 * log 2 (1+16)
=6 * 4.08746284125034
=24.74 kbps
