Answer 2

Answer:

A comparator is a device that compares two voltages or currents and outputs a digital signal indicating which is larger. It has two analog input terminals V_+\, and V_-\, and one binary digital output {\displaystyle V_{\rm {o}}\, }.

Explanation:

A comparator uses two signals as an input and provides one signal as an output. Often, the output is the arithmetical difference between the first input and the second. An operational amplifier is an example of a kind of comparator that then typically amplifies the difference.
