G5B11 - What is the ratio of PEP to average power for an unmodulated carrier?

Question

What is the ratio of PEP to average power for an unmodulated carrier?

Answer Options

  • A) 0.707
  • B) 1.00
  • C) 1.414
  • D) 2.00

Correct Answer: B


Explanation

Peak Envelope Power (PEP) is the maximum power achieved at the peak of the modulation envelope, and average power is the power averaged over a period of time (usually the longest modulation cycle).

For an unmodulated continuous wave (CW) carrier, the signal strength is constant; it is not varying. Therefore, the peak power (PEP) is the same as the average power, meaning the ratio of PEP to average power for an unmodulated carrier is 1.00.
