Editing Fall time

{{about|the electronics concept|the film|Fall Time}}

In [[electronics]], '''fall time''' ('''pulse decay time''') <math> t_f</math> is the [[time]] taken for the amplitude of a [[Pulse (signal processing)|pulse]] to decrease (fall) from a specified value (usually 90% of the peak value exclusive of [[overshoot (signal)|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 (signal)|ringing]] and hunting) are sometimes additionally stated when specifying fall time limits.
