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:
“Then one will say, ‘He is not dead, maybe,
Who was mortality’s unshaken lover
Who loved the spring upon the Tennessee,
The hushed fall and, again, the coming clover.’
None will recall, not knowing, the twisted roads
Where the mind wanders till the heart corrodes.”
—Allen Tate (1899–1979)
“Harvey: About this Voltaire.
Helene: What about him?
Harvey: How’d he ever get time to do all he did?
Helene: He lived to be old.
Harvey: Even so, how many letters did he write?
Helene: Oh, I don’t know exactly. Thousands.
Harvey: I can’t remember when I even wrote one.
Helene: You should try.
Harvey: It’s too late. I wouldn’t know where to send it.”
—Tom Waldman (d. 1985)
