What is the output PEP of an unmodulated carrier if the average power is 1060 watts?
- A.530 watts
- B.1060 watts (correct answer)
- C.1500 watts
- D.2120 watts
WhyAn unmodulated carrier with an average power of 1060 watts has an output PEP of 1060 watts. Because an unmodulated carrier's amplitude is constant, its peak envelope power equals its average power directly, so an average power of 1,060 watts means the PEP is also 1,060 watts, answer B. The other values would only apply if the carrier's envelope varied, which an unmodulated carrier's does not.
