Comparator

A comparator is an electronic device that compares two input signals or voltages and determines which one is higher or lower. Think of it as a decision-maker: when given two values, it outputs a signal indicating the larger or smaller one. This function is essential in many electronic systems, such as converting analog signals to digital, voltage level detection, or control systems. The comparator's response is typically very fast, making it reliable for real-time decision processes. In essence, it helps electronic circuits "compare" quantities and respond accordingly.
