The operation of an amplifier, a natural or artificial device intended to make a signal stronger. The amount of increase that an amplifier provides on the output side of the circuit is amplification. In other way we can say that Amplification is an increase in signal power or voltage produced by an amplifier in transmitting a signal from one point to another. The amount of gain is usually expressed in decibels above a reference level. Antenna gain is a measure of the effectiveness of a directional antenna as compared to a nondirectional antenna. Generally, an amplifier is any device that uses a small amount of energy to control a larger amount of energy. In popular use, the term today usually refers to an electronic amplifier, often as applied to audio applications. The relationship of the input to the output of an amplifier — usually expressed as a function of the input frequency — is called the transfer function of the amplifier, and the magnitude of the transfer function is termed the gain read less
