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 (18031882)
“Racism is when you have laws set up, systematically put in a way to keep people from advancing, to stop the advancement of a people. Black people have never had the power to enforce racism, and so this is something that white America is going to have to work out themselves. If they decide they want to stop it, curtail it, or to do the right thing ... then it will be done, but not until then.”
—Spike Lee (b. 1956)
“Talk of a divinity in man! Look at the teamster on the highway, wending to market by day or night; does any divinity stir within him? His highest duty to fodder and water his horses! What is his destiny to him compared with the shipping interests?”
—Henry David Thoreau (18171862)
“The lifelong process of caregiving, is the ultimate link between caregivers of all ages. You and I are not just in a phase we will outgrow. This is lifebirth, death, and everything in between.... The care continuum is the cycle of life turning full circle in each of our lives. And what we learn when we spoon-feed our babies will echo in our ears as we feed our parents. The point is not to be done. The point is to be ready to do again.”
—Paula C. Lowe (20th century)
