  1. Generator that produces sonic oscillations or alternating current

  Derived forms: oscillators

  Type of: generator

  Encyclopedia: Oscillator

• 
  [Electronics]
  A device that produces an alternating or pulsating current or voltage electronically. The term is sometimes used to describe any alternating-current-producing device other than an electromechanical generator.
  
• 
  [Finance]
  A technical analysis tool that is banded between two extreme values and built with the results from a trend indicator for discovering short-term overbought or oversold conditions. As the value of the oscillator approaches the upper extreme value the asset is deemed to be overbought, and as it approaches the lower extreme it is deemed to be oversold.
•

Examples

1. the negative sign means that energy is transferred from the oscillator to its environment.
2. sonic oscillator provides a very efficient means of breaking cells or organelles.
3. the dipole oscillator sum can be expressed in terms of the integrated photo absorption cross section.
4. there is, however, an additional contribution arising from those oscillators in the vicinity of the aperture's edge.
5. the case of a harmonic oscillator driven by sinusoidally varying force is an extremely important one in many branches.
