If level of modulation is increased ______________ power is increased?
Correct answer: B. Sideband
- A. Carrier
- B. Sideband
- C. Carrier as well as sideband
- D. None of the above
Explanation
For AM, carrier power stays fixed, while sideband power is proportional to the square of the modulation index. Thus increasing modulation increases sideband power only.
