A '''crystal''', in [[electronic]]s, is a device that creates a [[clock]] [[signal]] at a fixed and stable [[frequency]]. To do that, it relies on a fundamental property of some crystals, which is that they change shape ''very'' slightly when in an [[electric field]]. A [[voltage]] applied across the crystal causes a very slight change in its shape; when that voltage is eliminated, a very small secondary voltage is produced as it regains its original shape. In an appropriately arranged [[circuit]], this can be used to cause the crystal to oscillate at a fixed frequency. The exact frequency is set by the physical attributes of the crystal; it is therefore possible to 'tune' a crystal to a particular target frequency by physically adjusting the crystal, e.g. by delicately grinding it.
