Trigger when the time interval (△T) from when the rising or falling edge of the input signal passes
through the trigger level to when the next edge of opposite slope passes through the trigger level
is greater than the timeout time set, as shown in the figure below.
An example of use would be a digital system clock where an isolated pulse gets stretched in time.
Setting the trigger value to slightly more than half the clock's period could find such stretched
pulses.
