Definitions for "Average power"
total energy of an exposure divided by the duration of the exposure
Power averaged over time, which includes a complete on-off cycle. For example, a pulsed transmitter sends out RF energy in bursts. The peak power is averaged over the pulse time (duty cycle).
(pulse energy).(repetition rate) (units in W).
Keywords:  modulated, signal, over, time
The average over time of a modulated signal.
