Runt trigger is pulse amplitude triggering which crosses the first threshold level but doesn’t cross the second threshold level before the recross of the first one. Positive and negative pulse triggering is possible.

The oscillograms in the picture below show abnormal low pulse in the normal digital data stream. Such abnormal pulses can be glitches. However they can be caused by incorrectly designed supply circuits of some digital key as well.
