Schmittsäätimet
Schmittsäätimet, a term derived from German, literally translates to "Schmitt regulators" or "Schmitt controllers." In the context of electronics, it refers to circuits that exhibit hysteresis, a property where the output state depends not only on the current input but also on the input's past history. This hysteresis is often achieved through a Schmitt trigger.
A Schmitt trigger is a comparator circuit with two different switching thresholds for rising and falling input
This behavior makes Schmitt triggers useful for noise immunity. In the presence of noisy signals, a standard
