Decay Time

1. In computer operations, the time required for a pulse to fall to
one-tenth of its peak value. See rise time.
</dd>
2. In charge-storage tubes, the time interval during which the magnitude
of the stored charge decreases to a stated fraction of its initial value.
</dd>
The fraction is usually 1/e where e is the base of natural logarithms.

3. Approximately the lifetime of an orbiting object in a nonstable orbit.
