Font size:

amplitudes, plural;
  1. The maximum extent of a vibration or oscillation, measured from the position of equilibrium

  2. The maximum difference of an alternating electrical current or potential from the average value

  3. The angular distance of a celestial object from the true east or west point of the horizon at rising or setting

  4. Breadth, range, or magnitude
    • - the amplitude of the crime of manslaughter lies beneath murder
  5. The angle between the real axis of an Argand diagram and a vector representing a complex number

  1. (physics) the maximum displacement of a periodic wave
  2. the property of copious abundance
  3. greatness of magnitude
  4. Amplitude is a 2003 PlayStation 2 musical video game. It was developed by Harmonix and is the sequel to the game Frequency.
  5. The measure of something's size, especially in terms of width or breadth; largeness, magnitude; The maximum absolute value of the vertical component of a curve or function, especially one that is periodic; The maximum absolute value of some quantity that varies
  6. (Amplitudes) A measurement of size of vibration rather than speed or frequency.
  7. Generally refers to the maximum and minimum voltage attained by an alternating or pulsed current in each complete cycle or pulse of that current.
  8. the "size" or "height" of a tremor; the extend or breadth of a tremor's range.
  9. The height or degree of execution of a movement. In general, the higher the salto or the more breathtaking the movement, the better the amplitude and the score.
  10. The size or magnitude of a signal.
  11. The nonnegative scaler measurement of a sound wave’s peak magnitude during a frequency cycle or peak pressure variation.
  12. Sometimes used to describe the frequency of a mechanical movement, however seems more often used to describe the angle of oscillation of the balance wheel either side of its neutral position. This would therefore be measured in degrees, for example 'an amplitude of 270 degrees'.
  13. In Bryce, this refers to the intensity of the cloud definition. Increasing the amplitude will make cloud contours harder, while decreasing it will result in softer edged, more diffuse cloud formations.
  14. The maximum value of a varying waveform.
  15. The maximum absolute value of a periodic curve measured along its vertical axis (the height of a wave, in layman's terms).
  16. The strength of an electronic signal as measure by its waveform height. (Sound)
  17. the loudness of sound waves and electrical signals. Amplitude is measured in decibels (dB) or volts
  18. Amplitude is a term used to describe the amount of a signal. It can relate to volume in an audio signal or the amount of voltage in an electrical signal.
  19. A measurement of the distance from the highest to the lowest excursion of motion, as in the case of mechanical body in oscillation or the peak-to-peak swing of an electrical waveform.
  20. The signal level, or height.
  21. The instantaneous magnitude of an oscillating quantity such as sound pressure. The peak amplitude is the maximum value.
  22. The swing of a balance. The maximum swing from its normal at rest position to its furthest distance from rest (usually about 300 degrees).
  23. A measure of the height of the wave, which indicates the strength of the signal.
  24. The height of a wave. The amplitude of brainwaves derived from electroencephalography (EEG) changes with depth of sleep. For EEGs, amplitude is measured in voltage, typically microvolts.
  25. Maximum deviation from normal of any wave-like disturbance.
