Envelope peak power
The peak envelope power ( English peak envelope power , PEP ) is a term used in radio technology and expresses a power reading.
PEP denotes the high-frequency effective active power at the output of a transmitter output stage during a period of the high-frequency oscillation at the highest peak of the modulation envelope. In the case of an amplitude-modulated signal, this is shown at the brief moment at the period of the high frequency with the greatest amplitude deflection and in the diagram opposite as a red area under the signal curve.
The envelope peak power is used as a measure of the maximum effective power that is fed into the antenna cable . In addition, other, not to be confused power definitions are used in radio technology, such as the effective radiated power (ERP, EIRP), which describe the effectively radiated power of an antenna.
