Interview questions and answers on SCHMITT TRIGGER....

1)what do mean by a Schmitt trigger?
Schmitt trigger is a type of comparator which uses positive feedback. Schmitt trigger convert an sinusoidal signal to a square wave signal.

2)how many types of Schmitt trigger used?
There are two types Schmitt trigger are used.
1. Inverting Schmitt trigger.
2. Non-inverting Schmitt trigger.

3)what do you mean by threshold voltage of Schmitt trigger?
The input voltage of Schmitt trigger for which the Schmitt trigger changes their output is called threshold voltage.

4)what do you mean by hysteresis of Schmitt trigger?
Hysteresis is the voltage difference between turn-on and turn-off voltage of comparator.
