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:
“In all things I would have the island of a man inviolate. Let us sit apart as the gods, talking from peak to peak all round Olympus. No degree of affection need invade this religion.”
—Ralph Waldo Emerson (1803–1882)
“I am willing, for a money consideration, to test this physical strength, this nervous force, and muscular power with which I’ve been gifted, to show that they will bear a certain strain. If I break down, if my brain gives way under want of sleep, my heart ceases to respond to the calls made on my circulatory system, or the surcharged veins of my extremities burst—if, in short, I fall helpless, or it may be, dead on the track, then I lose my money.”
—Ada Anderson (1860–?)
“an age of unscrupulous and shameless book-making, it is a duty to give notice of the rubbish that cumbers the ground. There is no credit, no real power required for this task. It is the work of an intellectual scavenger, and far from being specially honourable.”
—Richard Holt Hutton (1826–1897)
“Only mediocrities progress. An artist revolves in a cycle of masterpieces, the first of which is no less perfect than the last.”
—Oscar Wilde (1854–1900)
