The time for the amplitude of system response to decay to 37% of its steady-state value after the removal of a steady-state step input signal.
Fall time is defined as the transition time from an output logic high to an output logic low and is measured in nanoseconds (nSec). This transition time is measured at specified voltage thresholds or at specified percentages of the output waveform amplitude. See rise time.
The time required for a signal to change from a high level (usually 90%) to a low level (usually 10%) of its base line-to-peak or peak-to-peak amplitude. (Also, see Rise Time.)
The amount of time it takes the output voltage to go from Logic '1' to logic '0'.
The elapsed time after a detector has responded to a test hydrocarbon and is removed and has recovered to 95% of its original baseline level or there is no detectable signal output.
Measurement of the interval during which a photo detector's signal and output current drops from 90 to 10 percent.
Time it takes the falling edge of a pulse to go from 90% of peak voltage to 10% of peak voltage.
The time required for a pulse to decrease from 90 percent to 10 percent of its maximum positive (negative) amplitude.
The time required for a signal to change from a large percentage (usually 90%) to a small percentage (usually 10%) of its peak-to-peak amplitude. See also RISE TIME.
Also called turn-off time. The time required for the trailing edge of a pulse to fall from 90% to 10% of its amplitude; the time required for a component to produce such a result. Typically measured between the 90% and 10% points or alternately the 80% and 20% points.
In electronics, fall time (pulse decay time) t_f\, is the time required for the amplitude of a pulse to decrease (fall) from a specified value (usually 90 percent of the peak value exclusive of overshoot or undershoot) to another specified value (usually 10 percent of the peak value exclusive of overshoot or undershoot). Limits on undershoot and oscillation (i.e. hunting) may need to be specified when specifying fall time limits.
