A comparator compares two input voltages
and gives you, as a result, which of the voltages is higher.
They are often used in controllers, where they compare the signal
of a sensor with a reference signal.
In this way, the controller is able come to a YES/NO decision.
You can find comparators, in, among other things,
analog-to-digital converters or frequency counters.
Here you find some experiments, highlighting the
operation and applications of comparators...
