Comparators

An amplifier is an electronic device that increases the strength of a signal. Amplifiers can be used to amplify a wide range of signals, including audio, video, and radio frequency signals. A comparator is a type of electronic circuit that compares two input signals and produces an output signal based on the relationship between the two inputs. Comparators are commonly used in digital circuits to detect and compare the levels of two signals. They can be used to determine whether one signal is greater than, less than, or equal to the other signal, and to produce an output signal that reflects this relationship. Unlike amplifiers, comparators do not amplify the input signals, but simply compare them and produce an output signal based on the comparison.
