oscillator definitions

WordNet (r) 3.0 (2005)

n
1: generator that produces sonic oscillations or alternating current

Merriam Webster's

noun Date: 1835 1. one that oscillates 2. a device for producing alternating current; especially a radio-frequency or audio-frequency generator

Britannica Concise

Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air resistance or friction. In electronic oscillators, electrons oscillate with a constant period and also require the addition of energy to replace energy loss. Electronic oscillators are used to generate alternating current and high-frequency currents for carrier waves in radio broadcasting. They are incorporated in a wide variety of electronic equipment.

Webster's 1913 Dictionary

Oscillator Os"cil*la`tor, n. One that oscillates; specif.: (a) (Elec.) Any device for producing electric oscillations; esp., an apparatus for generating electric waves in a system of wireless telegraphy. (b) (Mech.) An instrument for measuring rigidity by the torsional oscillations of a weighted wire.
