    Question

    In PAM technique which of the below attributes of the

    pulse is used to vary as the amplitude of message varies
    A Frequency of pulse Correct Answer Incorrect Answer
    B Width of pulse Correct Answer Incorrect Answer
    C Amplitude of pulse Correct Answer Incorrect Answer
    D Phase of pulse Correct Answer Incorrect Answer

    Solution

    • Why Correct: In Pulse Amplitude Modulation (PAM), the amplitude of each pulse is varied proportional to the instantaneous amplitude of the message signal.
    • Why Others are Wrong:
      • Frequency → PWM/PPM, not PAM.
      • Width → Pulse Width Modulation (PWM).
      • Phase → Pulse Phase Modulation (PPM).
