Fall Time

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)

    [I]f our reader should be neither informed nor amused, we shall be very sorry for his loss of time as well as our own.
    Sarah Fielding (1710–1768)
