As the modulation level is increased, the carrier power__________________?
Correct answer: B. Remains the same
- A. Is increased
- B. Remains the same
- C. Is decreased
- D. None of the above
Explanation
The carrier amplitude and power are set by the unmodulated carrier and do not change with modulation depth. Increasing modulation level only increases the power transferred to the sidebands.
