A logic input type that gives hysteresis or two various threshold voltage levels for falling and a rising edge is called Schmitt trigger. It is very useful to avoid errors in noisy input signals where the only aim is to get square wave signals. Schmitt trigger transforms an analog signal or sinusoidal signal to a digital signal. The output transition from low to high and high to low occur at various thresholds.
