Peak Power and Duty Cycle
In the case of a periodic signal of period, like a train of identical pulses, the instantaneous power is also a periodic function of period . The peak power is simply defined by:
.
The peak power is not always readily measurable, however, and the measurement of the average power is more commonly performed by an instrument. If one defines the energy per pulse as:
then the average power is:
.
One may define the pulse length such that so that the ratios
are equal. These ratios are called the duty cycle of the pulse train.

Famous quotes containing the words peak, power, duty and/or cycle:
“You know, I often thought that the gangster and the artist are the same in the eyes of the masses. They’re admired and hero-worshipped but there is always present underlying desire to see them destroyed at the peak of their glory.”
—Stanley Kubrick (b. 1928)
“Another success is the post-office, with its educating energy augmented by cheapness and guarded by a certain religious sentiment in mankind; so that the power of a wafer or a drop of wax or gluten to guard a letter, as it flies over sea over land and comes to its address as if a battalion of artillery brought it, I look upon as a fine meter of civilization.”
—Ralph Waldo Emerson (1803–1882)
