About Logic Comparators

Logic Comparators

A logic comparator is a type of electronic circuit used to compare two logic values, or logic levels and produce a single output based on the result. A logic comparator is usually designed to detect the presence or absence of a particular logic level on its inputs, and output a single logic level to indicate the results of the comparison. Generally speaking, a logic comparator is either a digital or analog circuit and operates by comparing two signals (i.e. analog or digital) and outputting a single result depending on the comparison. Logic comparators are commonly used in microcontrollers, digital signal processors (DSPs), and other digital logic devices to determine if a particular logic level exists at the inputs. Additionally, logic comparators may also be used to quickly identify whether two logic levels, or logic signals, differ from each other.
