Amplifier vs. Amplitude

Amplifiernoun

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

Amplifiernoun

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

Amplifiernoun

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

Amplifiernoun

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

Amplifiernoun

A lens that enlarges the field of vision.

Amplifiernoun

One who or that which amplifies.

Amplifiernoun

electronic equipment that increases strength of signals passing through it

Amplifier

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.

Amplitudenoun

The measure of something's size, especially in terms of width or breadth; largeness, magnitude.

Amplitudenoun

(mathematics) The maximum absolute value of the vertical component of a curve or function, especially one that is periodic.

Amplitudenoun

(physics) The maximum absolute value of some quantity that varies.

Amplitudenoun

(astronomy) The arc of the horizon between the true east or west point and the center of the sun, or a star, at its rising or setting. At the rising, the amplitude is eastern or ortive: at the setting, it is western, occiduous, or occasive. It is also northern or southern, when north or south of the equator.

Amplitudenoun

(astronomy) The arc of the horizon between the true east or west point and the foot of the vertical circle passing through any star or object.

Amplitudenoun

(firearms) The horizontal line which measures the distance to which a projectile is thrown; the range.

Amplitudenoun

State of being ample; extent of surface or space; largeness of dimensions; size.

Amplitudenoun

Largeness, in a figurative sense; breadth; abundance; fullness.

Amplitudenoun

The arc of the horizon between the true east or west point and the center of the sun, or a star, at its rising or setting. At the rising, the amplitude is eastern or ortive: at the setting, it is western, occiduous, or occasive. It is also northern or southern, when north or south of the equator.

Amplitudenoun

The horizontal line which measures the distance to which a projectile is thrown; the range.

Amplitudenoun

The extent of a movement measured from the starting point or position of equilibrium; - applied especially to vibratory movements.

Amplitudenoun

An angle upon which the value of some function depends; - a term used more especially in connection with elliptic functions.

Amplitudenoun

(physics) the maximum displacement of a periodic wave

Amplitudenoun

the property of copious abundance

Amplitudenoun

greatness of magnitude

Amplitude

The amplitude of a periodic variable is a measure of its change in a single period (such as time or spatial period). There are various definitions of amplitude (see below), which are all functions of the magnitude of the differences between the variable's extreme values.
