    About Logic - Comparators

    Comparators are electronic circuits used to compare the magnitudes of two analog or digital input signals and produce a corresponding output based on the result of the comparison. They determine whether one input signal is greater than, less than, or equal to the other, generating logical output states indicative of the comparison outcome. Comparators are commonly used in control systems, instrumentation, data acquisition, and signal processing applications to monitor, measure, and control analog and digital signals based on predefined threshold levels.
