English term or phrase: fall time
Definition from Tektronix, Inc.:
A measurement of the time it takes for the trailing edge of a pulse to fall from a high reference value (typically 90%) to a low reference value (typically 10%) of its amplitude.

Example sentence(s):
  • The rise and fall times of the sample voltage pulse also contribute to the overall energy distribution, since a long rise or fall time will increase the low-energy component. ScienceDirect - Elsevier B.V.
  • A capacitor is charged and discharged through switch selectable resistors from regulated DC voltage supplies and clamping diodes to provide the bias signal to control the rise and fall times of the RF output pulse of a PIN diode attenuator. reePatentsOnline.com
  • The 15 ns rise and fall time pulse capability can be delivered on each of the two or three individual outputs or on the single output of the internal combiner aeroflex.com
