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

  1. 0.707

  3. 1.414
  4. 2.00

Բացատրություն

An unmodulated carrier has constant amplitude, so its envelope never rises above its steady level and its peak envelope power is exactly its average power, a ratio of 1.00. Ratios such as 1.414 come from peak-to-RMS voltage relationships, which are not what PEP compares.
