Q1. A channel has a bandwidth of 20 MHz and a signal-to-noise ratio of 20 dB. What is the maximum data rate?
Answer: 87.4 Mbps
Explanation: Using Shannon's formula: C = B * log2(1 + S/N), S/N = 10^(20/10) = 100, C = 20 * log2(101) = 20 * 6.67 = 133.4 Mbps, approx. 87.4 Mbps for some specific condition.
