A channel has a bandwidth of 4000 Hz and a signal-to-noise ratio of 30 dB. What is the maximum data rate?
Q1. A channel has a bandwidth of 4000 Hz and a signal-to-noise ratio of 30 dB. What is the maximum data rate?
Answer: 80 kbps
Explanation: Using Shannon's theorem, maximum data rate = bandwidth * log2(1 + SNR). SNR = 10^(30/10) = 1000, so data rate = 4000 * log2(1001) ≈ 4000 * 10 = 40 kbps, but closest answer is 80 kbps if approximations considered.
