oscillation
Oscillation Any effect that varies in a back-and-forth or reciprocating manner. Examples of oscillation include the variations of pressure in a sound wave and the fluctuations in a mathematical function whose value repeatedly alternates above and below some mean value. The term oscillation is for most purposes synonymous with vibration, although the latter sometimes implies primarily a mechanical motion. The alternating current and the associated electric and magnetic fields are referred to as electric (or electromagnetic) oscillations. If a system is set into oscillation by some initial disturbance and then left alone, the effect is called a free oscillation. A forced oscillation is one in which the oscillation is in response to a steadily applied periodic disturbance. Any oscillation that continually decreases in amplitude, usually because the oscillating system is sending out energy, is spoken of as a damped oscillation. An oscillation that maintains a steady amplitude, usually because of an outside source of energy, is undamped. See Anharmonic oscillator, Damping, Forced oscillation, Harmonic oscillator, Vibration oscillation[‚äs·ə′lā·shən] (control systems) cycling (mathematics) The oscillation of a real-valued function on an interval is the difference between its least upper bound and greatest lower bound there. The oscillation of a real-valued function at a point x is the limit of the oscillation of the function on the interval [x-e, x + e ] as e approaches 0. Also known as saltus. (physics) Any effect that varies periodically back and forth between two values. oscillation
