Experiment 9 - The Inverting Schmitt Trigger
As with the normal comparator circuit you can set up the
Schmitt trigger as an inverting Schmitt trigger.
To set up the inverting Schmitt trigger, you swap again the inputs
Vin and
VRef.
Note: The feedback resistor R3
is now connected to
VRef!

Hence, you get the typical signal profile of an
inverting Schmitt trigger...
