To experience this, exchange the feedback resistor with a resistance value of R3 =100 kΩ...
The width of the hysteresis is significantly smaller...
Do you want to know how you determine the resistance of R3, you find this information in the topic "Schmitt-Trigger".
This circuit has many applications. It is used in electric ovens or twilight switches of street lighting. More on that later.
Analogous to the simple comparator circuits, this circuit is referred to as a non-inverting Schmitt trigger.
In the next step you get to know the inverting Schmitt trigger...
