Runt pulse
In digital circuits, a runt pulse is a narrow pulse that, due to non-zero rise and fall times of the signal, does not reach a valid high or low level. A runt pulse may occur when switching between asynchronous clocks; or as the result of a race condition in which a signal takes two separate paths through a circuit, which may have different delays, and is then recombined to form a glitch; or when the output of a flip-flop becomes metastable.
Example
Some oscilloscopes provide a method for triggering on runt pulses. The oscilloscope triggers when the signal crosses one of two voltage thresholds, but not both.[1]
gollark: Ah yes, indirectly then. Swap that for "in useful quantities" or "without expending tons of time/resources" if you like.
gollark: I didn't mention "money".
gollark: What?
gollark: (Sidenote: interestingly, apparently the development of farming actually led to significantly *worse* life for people for quite a long time, because it allowed much more population per land area, causing people to end up at a subsistence level and quite malnourished and stuff)
gollark: Modern supply chains are complex, and while we could not have those you would then lose out on stuff like microelectronics, medical things, and the economies of scale meaning you can have nice things cheaply.
