An amplifier can be considered to be any device that uses a small amount of energy to control a larger amount, although the term today usually refers to an electronic amplifier. 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.

Transfer function: A transfer function is a mathematical representation of the relation between the input and output of a linear time-invariant system. The transfer function is commonly used in the analysis of single-input single-output analog circuits. It is mainly used in linear, time-invariant system theory, signal...
