What is Schmitt trigger?

A circuit whose switching threshold differs for rising and falling inputs (hysteresis). Its output does not chatter even with slowly changing or noisy signals.

Field: Analog and electronic circuits

Schmitt trigger in the explanations

A Schmitt trigger has a higher threshold for rising inputs and a lower one for falling inputs; the difference is hysteresis.
