Overmodulation (amplitude) occurs when signal amplitude is _____________ carrier amplitude?
Correct answer: B. Greater than
- A. Equal to
- B. Greater than
- C. Less than
- D. None of the above
Explanation
Amplitude overmodulation occurs when the modulation index exceeds 1, meaning the signal amplitude is greater than the carrier amplitude. Equal amplitudes represent 100% modulation, not overmodulation.
