A) an integrator.
B) a comparator.
C) a differentiator.
D) a multiplexer.

Question

Quizplus · Accepted Answer

A comparator is a basic electronic device that compares the voltage or current level of two inputs and outputs a positive voltage when the input voltage exceeds a certain threshold level. It is commonly used in a variety of electronic circuits, including digital-to-analog converters and voltage regulators. An integrator is a circuit that integrates the input voltage over time, a differentiator is a circuit that differentiates the input voltage, and a multiplexer is a device that selects between multiple inputs and outputs a single output.
