amplitude definition
amplitude. 1  the state or quality of being ample, especially as to breadth or width; largeness; greatness of extent. 2  large or full measure; abundance; copiousness. 3  mental range, scope, or capacity. 4  Physics. the absolute value of the maximum displacement from a zero value during one period of an oscillation. To conclude: no man can by care taking (as the Scripture saith) add a cubit to his stature, in this little model of a man's body; but in the great frame of kingdoms and commonwealths, it is in the power of princes or estates, to add amplitude and greatness to their kingdoms; for by introducing such ordinances, constitutions, and customs, as we have now touched, they may sow greatness to their posterity and succession. Amplitude definition, the state or quality of being ample, especially as to breadth or width; largeness; greatness of extent. See more. Historical Examples. 1  The amplitude is the width of swing of the individual particles of the waves. 2  The wealth of design and amplitude of the series are truly amazing. 3  The one is marked by energy and accuracy, the other by amplitude. 4  The harbor of New York gives, first of all, the impression of amplitude. Then she put upon her the white frock that Tess had worn at the club-walking, the airy fulness of which, supplementing her enlarged COIFFURE, imparted to her developing figure an amplitude which belied her age, and might cause her to be estimated as a woman when she was not much more than a child. amplitude definition. In physics, the height of a crest (or the depth of a trough) of a wave. One half the full extent of a vibration, oscillation, or wave. The amplitude of an ocean wave, for example, is the maximum height of the wave crest above the level of calm water, or the maximum depth of the wave trough below the level of calm water. The amplitude of a pendulum swinging through an angle of 90° is 45°. See more at wave. Physics One half the full extent of a vibration, oscillation, or wave. The amplitude of an ocean wave is the maximum height of the wave crest above the level of calm water, or the maximum depth of the wave trough below the level of calm water. The amplitude of a pendulum swinging through an angle of 90° is 45°. Compare frequency. Electronics The amount by which a voltage or current changes from zero or an average value. But the story would include a chain of events extending over the better part of two centuries, and, written out with reasonable amplitude, would fill a bigger folio volume, or a longer series of duodecimos, than could prudently be appropriated to the annals of all New England during a similar period. The amplitude is the width of swing of the individual particles of the waves. Fragments of science, V. 1-2 John Tyndall The wealth of design and amplitude of the series are truly amazing.
