Fr.: oscillateur harmonique
Any oscillating particle in harmonic motion.
→ harmonic; → oscillator.
Fr.: oscillateur hertzien
An electrical system used for the production of → electromagnetic waves. It consists of two equal → capacitors connected to two electrodes with a → spark gap between the electrodes. The system is connected to an → induction coil. When the induction coil is activated, electromagnetic waves are generated across the spark gap. See also → Hertz experiment.
→ hertz (Hz); → oscillator.

Fr.: oscillateur local
The oscillator in a heterodyne or superheterodyne radio receiver which produces the radio frequency oscillations with which the received wave is combined.
→ local; → oscillator.
A device for producing sonic or ultrasonic pressure waves in a medium. A device with no rotating parts for converting direct current into alternating current.
Agent noun of → oscillate.
Fr.: force d'oscillateur
A quantum-mechanical measure of the probability that a specific atomic transition will occur. It is used in the equation for the absorption coefficient of a spectral line. Also known as f value.
→ oscillator; → strength.
simple harmonic oscillator
navešgar-e hamâhang-e sâdé
Fr.: oscillateur harmonique simple
An oscillator whose force is proportional to its extension, according to → Hooke's law. The way the oscillator moves is called → simple harmonic motion.
→ simple; → harmonic; → oscillator.
