Which of the following formulas correctly represents the Shannon-Hartley channel capacity theorem for a channel with bandwidth B (in Hz), signal power S, and noise power N?
- 1C = B log2(1 + SN) bits per second
- 2C = B / log2(1 - N/S) bits per second
- 3C = B log2(1 + S/N) bits per second✓
- 4C = B log2(1 - N/S) bits per second
Correct answer
C = B log2(1 + S/N) bits per second
