At 100% modulation, the power in each sideband is _____________ of that of carrier?
Correct answer: D. 25%
- A. 50%
- B. 40%
- C. 60%
- D. 25%
Explanation
The power in each AM sideband is m²P_c/4, where m is the modulation index. At 100% modulation, m equals one, so each sideband has P_c/4, or 25% of the carrier power.
