For an overmodulated signal, what is the value of the modulation index?

  1. 1
  2. 0
  3. Less than 1
  4. Greater than 1

Correct answer: Greater than 1

Solution

An overmodulated signal occurs when the modulation index exceeds 1, leading to distortion and loss of signal integrity, as the amplitude of the modulating signal surpasses the carrier signal's amplitude.
