An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current).

An amplifier functions by taking power from a power supply and controlling the output to match the input signal shape but with a larger amplitude.

In this sense, an amplifier modulates the output of the power supply based upon the properties of the input signal.

An amplifier is effectively the opposite of an attenuator: while an amplifier provides gain, an attenuator provides loss.

Security is the degree of resistance to, or protection from, harm.
