Amplifier vs. Oscillator — What's the Difference?

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). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output.

To swing back and forth with a steady, uninterrupted rhythm.

One that amplifies, enlarges, or extends.

To waver, as between conflicting opinions or courses of action; vacillate

An electronic device that is used to increase the magnitude of an electrical signal.

(Physics) To vary between alternate extremes, usually within a definable period of time.

A device that is used to increase the magnitude of an information-carrying signal.

A tuned electronic circuit used to generate a continuous output waveform.

Anything that amplifies, or makes something larger or more intense.

An instrument for measuring rigidity by the torsional oscillations of a weighted wire.

(linguistics) An adverb that adds intensity, such as "really" or "totally".

(cellular automata) A pattern that returns to its original state, in the same orientation and position, after a finite number of generations.

(electronics) An appliance or circuit that increases the strength of a weak electrical signal without changing the other characteristics of the signal.

One that oscillates

(music) A portable encasement that houses a large speaker, used to amplify voices and musical instruments at live performances.

An instrument for measuring rigidity by the torsional oscillations of a weighted wire.

A lens that enlarges the field of vision.

Generator that produces sonic oscillations or alternating current

One who or that which amplifies.

Electronic equipment that increases strength of signals passing through it
