  1. Question 1

    Q1. A cable has a bandwidth of 100 MHz and uses 64-QAM modulation. What is the maximum data rate?

    • A) 600 Mbps
    • B) 800 Mbps
    • C) 1200 Mbps
    • D) 1600 Mbps

    Answer: 1200 Mbps

    Explanation: Using Shannon's theorem or Nyquist theorem for max data rate, for 64-QAM, log2(64) = 6, so data rate = 2 * 100 MHz * 6 = 1200 Mbps.
