Amplifier $140.19 Generally, an amplifier or simply amp, is any device that changes, usually increases, the amplitude of a signal. The relationship of the input to the output of an amplifierusually expressed as a function of the input frequencyis called the transfer function of the amplifier, and the magnitude of the transfer function is termed the gain. In popular use, the term usually describes an electronic amplifier, in which the input signal is usually voltage or current. In audio applications, amplifiers operate loudspeakers used in PA systems to make the human voice louder or play recorded music. Amplifiers may be classified according to the input (source) they are designed to amplify (such as a guitar amplifier, to perform with an electric guitar), the device they are intended to drive (such as a headphone amplifier), the frequency range of the signals (Audio, IF, RF, and VHF amplifiers, for example), whether they invert the signal (inverting amplifiers and noninverting amplifiers), or the type of device used in the amplification (valve or tube amplifiers, FET amplifiers, etc.).
