Resonator

A resonator is a accessory or arrangement that exhibits resonance or beating behavior, that is, it by itself oscillates at some frequencies, alleged its beating frequencies, with greater amplitude than at others. The oscillations in a resonator can be either electromagnetic or automated (including acoustic). Resonators are acclimated to either accomplish after-effects of specific frequencies or to baddest specific frequencies from a signal. Musical instruments use acoustic resonators that aftermath complete after-effects of specific tones.

A atrium resonator, usually acclimated in advertence to electromagnetic resonators, is one in which after-effects abide in a alveolate amplitude central the device. Acoustic atrium resonators, in which complete is produced by air cavernous in a atrium with one opening, are accepted as Helmholtz resonators.
