Question 2 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)
=6log 2 (1+16)
=6*log 2 (17)
=6*4.08=24.48
In presence of Gaussian band-limited white noise, Shannon Hartley theorem gives the
maximum data rate capacity C = B log 2 (1+ S/N)
=6log 2 (1+16)
=6*log 2 (17)
=6*4.08=24.48
