According to Shannon’s capacity formula for an AWGN channel, channel capacity is?

  • AC=B log2(1+S/N)
  • BC=2B only
  • CC=B(S/N) without logarithm
  • DC=S/N divided by B
Report an error
Correct Answer: A. C=B log2(1+S/N)
Explanation: Shannon's formula gives the theoretical maximum reliable information rate C=B log2(1+S/N) for an ideal band-limited AWGN channel.
