A comparator is sometimes called a limit detector because a positive output indicates that the input voltage exceeds a specific limit.

Question

Quizplus · Accepted Answer

A comparator compares two input voltages and produces a binary output indicating which voltage is larger. If the input voltage exceeds a specific limit, the comparator outputs a positive voltage, indicating that the input voltage is greater than the reference voltage. Therefore, a comparator can be called a limit detector.
