  1. Question 1

    Q1. What is the maximum data rate of a channel with 4 signal levels and a bandwidth of 3000 Hz?

    • A) 6000 bps
    • B) 12000 bps
    • C) 24000 bps
    • D) 48000 bps

    Answer: 24000 bps

    Explanation: Using Nyquist formula: Data Rate = 2 * Bandwidth * log2(L), where L = 4, Data Rate = 2 * 3000 * log2(4) = 2 * 3000 * 2 = 12000 bps.
