  1. Question 1

    Q1. A channel with a bandwidth of 4 kHz and an SNR of 30 dB has a maximum data rate of?

    • A) 40 kbps
    • B) 32 kbps
    • C) 20 kbps
    • D) 16 kbps

    Answer: 40 kbps

    Explanation: Using Shannon's theorem, max data rate = 4000 * log2(1 + 10^(30/10)) = 4000 * log2(1001) ≈ 39865 bps or 40 kbps.
