AMPLITUDE

n.[L. amplitudo, from amplus, large. ] 1. Largeness; extent, applied to bodies; as, the amplitude of the earth.
2. Largeness; extent of capacity or intellectual powers; as, amplitude of mind.
3. Extent of means or power; abundance; sufficiency.
Amplitude, in astronomy, is an arch of the horizon intercepted between the east and west point, and the center of the sun or star at its rising or setting. At the rising of a star, 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.
Amplitude of the range, in projectiles, is the horizontal line subtending the path of a body thrown, or the line which measures the distance it has moved.
Magnetical amplitude is the arch of the horizon between the sun or a star, at rising or setting, and the east or west point of the horizon, by the compass. The difference between this and the true amplitude is the variation of the compass.

 

Webster's 1913 Dictionary

AMPLITUDE

Am "pli *tude, n. Etym: [L. amplitudo, fr. amplus: cf. F. amplitude. See Ample. ]

 

1. State of being ample; extent of surface or space; largeness of dimensions; size. The cathedral of Lincoln. .. is a magnificent structure, proportionable to the amplitude of the diocese. Fuller.

 

2. Largeness, in a figurative sense; breadth; abundance; fullness. (a ) Of extent of capacity or intellectual powers. "Amplitude of mind. " Milton. "Amplitude of comprehension. " Macaulay. (b ) Of extent of means or resources. "Amplitude of reward. " Bacon.

 

3. (Astron.) (a ) 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. (b ) 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.

 

4. (Gun. )

 

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

 

5. (Physics )

 

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

 

6. (math. )

 

Defn: An angle upon which the value of some function depends; -- a term used more especially in connection with elliptic functions. Magnetic amplitude, the angular distance of a heavenly body, when on the horizon, from the magnetic east or west point as indicated by the compass. The difference between the magnetic and the true or astronomical amplitude (see 3 above ) is the "variation of the compass. "

 

New American Oxford Dictionary

amplitude

am pli tude |ˈampliˌt (y )o͞od ˈæmpləˌt (j )ud | ▶noun 1 Physics the maximum extent of a vibration or oscillation, measured from the position of equilibrium. • the maximum difference of an alternating electrical current or potential from the average value. 2 Astronomy the angular distance of a celestial object from the true east or west point of the horizon at rising or setting. 3 breadth, range, or magnitude: the amplitude of the crime of manslaughter lies beneath murder. 4 Mathematics the angle between the real axis of an Argand diagram and a vector representing a complex number. ORIGIN mid 16th cent. (in the senses ‘physical extent ’ and ‘grandeur ’): from Latin amplitudo, from amplus ‘large, abundant. ’

 

amplitude modulation

am pli tude mod u la tion (abbr.: AM ) ▶noun the modulation of a wave by varying its amplitude, used chiefly as a means of radio broadcasting, in which an audio signal is combined with a carrier wave. Often contrasted with frequency modulation.
