This circuit has similar function with inverting comparator with hysteresis, but the  output is not inverted. The output will be high if the input is higher than the upper threshold point, and the output will be low if the input is below the lower threshold point. Here is the circuit’s schematic diagram:

What will happen if [...]

Comparator with hysteresis (Schmidt trigger) can be built using  LM339, LM239, LM2901, LM2901V, NCV2901, or MC3302  quad single supply comparator integrated circuit chips. Here is the circuit’s schematic diagram and formula:

This circuit’s output will swing to high or low using two threshold values. If the last output is high, then the output can be changed [...]
