+Peak envelope delivery or PEP is the average power of onc ecomplete RF cycle at
+the peak of the singal envelope. It is important to note that it IS NOT the
+power at the peak of an RF cycle during a peak of the signal's envelope.
+
+PEP is used as it is a convient way to portray the max power of an amplitude
+modulated signal.
+
+== Calcuation ==
+
+To calculate PEP, you need to know the [[Impedance]] and [[AC#RMS|RMS]].
+You can also calcuate it using the Peak Envelope Power (PEV), or the peak
+amplitude of one side band, or the Peak to Peak voltage (V,,p-p,,). V,,p-p,,
+is found by doubling the PEV, or taking the max voltage of both sidebands.
+
+PEP is euqal to the average power if an amplitude-modulated signal is not
+modulated.
+
+
+The way to calculate it is shown below
+
+PEP = V,,RMS,,^2 / R
+
+PEP = ((0.707 * V,,p-p,,) / 2)^2 / R
+
+PEP = (PEV * 0.707)^2 / R
+
+Where R is the loads [[Impedance]]. For example,
+
+Peak envelope voltage (PEV) is 50V across a 50ohm load. PEP is
+
+PEP = (50 * 0.707)^2 / 50
+
+PEP = 25W
+
+A 50ohm load is dissipating a 1200W PEP, the RMS voltage is
+
+1200 = V,,RMS,,^2 / 50
+
+60000 = V,,RMS,,^2
