  1. Question 1

    Q1. What is the maximum data rate for a noiseless channel with 4 signal levels and 2000 Hz bandwidth?

    • A) 8000 bps
    • B) 4000 bps
    • C) 16000 bps
    • D) 12000 bps

    Answer: 8000 bps

    Explanation: Using Nyquist formula: Data Rate = 2 * Bandwidth * log2(L), Data Rate = 2 * 2000 * log2(4) = 2 * 2000 * 2 = 8000 bps.
