Peak envelope power

Representation of the peak envelope power (PEP) using the example of an AM-modulated signal. The PEP is the power area shown in red.

Peak envelope power (PEP) is the average power over a single radio frequency cycle at the crest of the modulation. This is a Federal Communications Commission definition. PEP is normally considered the occasional or continuously repeating crest of the modulation envelope under normal operating conditions. The United States FCC uses PEP to set maximum power standards for radio transmitters.[1]
