Hi
I'd wondered about this. Here's a link that
gives an answer - plus diagrams
http://hyperphysics.phy-astr.gsu.edu/Hbase/Electronic/schmitt.html
The Schmitt Trigger
The Schmitt trigger is a comparator application which switches the output negative when the input passes upward through a positive reference voltage. It then uses negative feedback to prevent switching back to the other state until the input passes through a lower threshold voltage, thus stabilizing the switching against rapid triggering by noise as it passes the trigger point.
