What is the role of a Comparator in digital circuits?

A Comparator plays a crucial role in digital circuits by comparing two voltage or current levels and producing a corresponding output that indicates which of the two inputs is greater. This output is typically a binary result – either high (indicating one input is higher) or low (indicating that the other input is higher). Comparators are fundamental components used in various applications, such as analog-to-digital converters, where they help translate varying voltage levels into discrete digital values.

In digital systems, precise comparisons are essential for decision-making processes, establishing thresholds, and enabling logical operations based on the relative magnitude of input signals. The ability to assess and compare inputs allows for effective data processing and system control in various electronic applications.
