A comparator circuit that detects when the input voltage is between two limits is called
A) a limit comparator.
B) a dual detector.
C) a window comparator.
D) an input limiter.

Question

Quizplus · Accepted Answer

A window comparator detects when the input voltage is within a certain range or "window" of two limits, which is the function described in the question. Choice A, a limit comparator, typically only detects when the input voltage exceeds a single limit. Choice B, a dual detector, is not a commonly used term in the context of comparator circuits. Choice D, an input limiter, typically refers to a circuit that limits the magnitude of the input voltage, but does not specifically detect when the voltage is between two limits.
