In electronics, fall time (pulse decay time) is the time taken for the amplitude of a pulse to decrease (fall) from a specified value (usually 90% of the peak value exclusive of overshoot or undershoot) to another specified value (usually 10% of the maximum value exclusive of overshoot or undershoot).
Limits on undershoot and oscillation (also known as ringing and hunting) are sometimes additionally stated when specifying fall time limits.
Famous quotes containing the words fall and/or time:
“mouth to mouth, the covers
pulled over our shoulders
we drowse as horses drowse afield,
in accord; though the fall cold
surrounds our warm bed, and though
by day we are singular and often lonely.”
—Denise Levertov (b. 1923)
“So much of our time is preparation, so much is routine, and so much retrospect, that the pith of each man’s genius contracts itself to a very few hours.”
—Ralph Waldo Emerson (1803–1882)
