A voltage comparator compares two voltages and returns as a result which voltage is higher.
Consider the circuit with the LM311 voltage comparator...

Turning on the potentiometer P1...
The switch-on and switch-off points coincide...
The voltage comparator is therefore not a Schmitt trigger! How do you turn a voltage comparator into a Schmitt trigger...? |
