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:
“Mrs. Zajac knows you didn’t try. You don’t just hand in junk to Mrs. Zajac. She’s been teaching an awful lot of years. She didn’t fall off the turnip cart yesterday. She told you she was an old-lady teacher.”
—Christine Zajac, U.S. fifth-grade teacher. As quoted in Among Schoolchildren, “September” section, part 1, by Tracy Kidder (1989)
“A man who sees another man on the street corner with only a stump for an arm will be so shocked the first time he’ll give him sixpence. But the second time it’ll only be a threepenny bit. And if he sees him a third time, he’ll have him cold-bloodedly handed over to the police.”
—Bertolt Brecht (1898–1956)
