PEP output power equivalency

Definition of PEP:

PEP (peak envelope power) is the average power during one RF cycle at the peak of the signal's envelope. PEP measures the maximum power of an amplitude-modulated signal.

PEP is equal to the average power if an amplitude-modulated signal is not modulated. With no input modulation (such as voice), only the carrier wave remains.

For FM signals, PEP is always equal to average power of the signal.

With an AM or SSB modulated signal, PEP is equal to the transmitter's output when the modulating input (voice for example) is at the maximum amplitude (voice level, for example).
