oscillated, past tense; oscillated, past participle; oscillates, 3rd person singular present; oscillating, present participle;
  1. Move or swing back and forth at a regular speed
    • - a pendulum oscillates about its lowest point
  2. Waver between extremes of opinion, action, or quality
    • - he was oscillating between fear and bravery
  3. Vary in magnitude or position in a regular manner around a central point

  4. (of a circuit or device) Cause the electric current or voltage running through it to behave in this way

  1. hover: be undecided about something; waver between conflicting positions or courses of action; "He oscillates between accepting the new position and retirement"
  2. move or swing from side to side regularly; "the needle on the meter was oscillating"
  3. (oscillating) oscillatory: having periodic vibrations
  4. (oscillation) the process of oscillating between states
  5. (oscillation) (physics) a regular periodic variation in value about a mean
  6. (oscillation) cycle: a single complete execution of a periodically repeated phenomenon; "a year constitutes a cycle of the seasons"
  7. Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples include a swinging pendulum and AC power. ...
  8. (Oscillation (differential equation)) In mathematics, in the field of ordinary differential equations, a non trivial solution to an ordinary differential equation
  9. (Oscillation (mathematics)) In mathematics, oscillation is the behaviour of a sequence of real numbers or a real-valued function, which does not converge, but also does not diverge to +∞ or -∞; that is, oscillation is the failure to have a limit, and is also a quantitative measure for that.
  10. To swing back and forth, especially if with a regular rhythm; To vacillate between conflicting opinions, etc
  11. (Oscillating) A method of winding narrow strip steel over a much wider roll. Customers want to have as much steel on a coil as will fit in their machines, so they can spend less time moving the material and more time using it. ...
  12. (Oscillating) the practice of winding coils so that the outside walls of the coil appear to be like waves (steel is wound in and out by moving the recoiler mandrel back and forth). In the extreme you can get a telescoping affect which is deemed a defect. ...
  13. (OSCILLATION) rhythmic periodic motion.
  14. Oscillation is repetitive back and forth movement such as a vibration.
  15. Complete oscillation or rotation movement of the balance, formed by two vibrations.
  16. (Oscillation) The variation, usually with time, of the magnitude of quantity with respect to a specified reference when the magnitude is alternately greater and smaller than the reference.
  17. (OSCILLATION) The regular movement of a body, such as a balance wheel or pendulum, between two given points from one extreme to the other and back again. Anything that oscillates with regularity can be used as a timekeeper.
  18. (Oscillation) motion between extremes: the act of moving backward and forward between two extreme points. [Early 18th century. From Latin oscillat- , the perfect participle stem of oscillare “to swing,” from oscillum “swing, mask” (of Bacchus hung as a charm on a tree to swing), from os 1.]
  19. (oscillation) Vibration of a sound or radio wave.
  20. (OSCILLATION) The variation with the time, alternately increasing and decreasing, of (a) some feature of an audible sound, such as the sound pressure, or (b) some feature of a vibrating solid object, such as the displacement of its surface.
  21. (Oscillation) A flow of electricity changing periodically from a maximum to a minimum; a flow periodically changing direction.
  22. (Oscillation) A sustained condition of continuous operation where the circuit outputs a constant signal at a frequency determined by circuit constants and as a result of positive or regenerative feedback.
  23. (Oscillation) In portable coolers, this usually refers to swinging fans or louvers that provide enhanced cooling and fanning performance, as well as improved air circulation.
  24. (Oscillation) The movement of a machine while winding up labels that moves them back and forth so the roll with hold together better.
  25. (Oscillation) The movement, usually vertically, of a suspended bridge deck in the wind.
