A 50 kW carrier is to be amplitude modulated to a level of 85%. What is the carrier power after modulation ?
Correct answer: A. 50 kW
- A. 50 kW
- B. 5 kW
- C. 8 kW
- D. 25 kW
Explanation
In amplitude modulation, the carrier power remains constant at all modulation depths; only the sideband power changes. Therefore the carrier remains 50 kW, while 85% modulation increases the sideband power.
