Amplitude definition, the state or quality of being ample, especially as to breadth or width; largeness; greatness of extent. In older texts, the phase of a period function is sometimes called the amplitude.



Definition of amplitude 1 : the extent or range of a quality, property, process, or phenomenon: such as a : the extent of a vibratory movement (as of a pendulum) measured from the mean position to an extreme signal level - the amplitude level of the desired signal.

In an electrical circuit operating on alternating current (ac), amplitude is measured as the Voltage (V) level and is expressed as +V and V, depending on the direction of the current. magnitude - the property of relative size or extent (whether large or small); "they tried to predict the magnitude of the explosion"; "about the magnitude of a small pea". Amplitude of comprehension.. Of extent of meansor resources. The amplitude of a periodic variable is a measure of its change in a single period (such as time or spatial period).

amplitude - greatness of magnitude.
