A device that generates high-frequency pulses (usually a square wave) for purposes of synchronization and event timing.Most are crystal oscillators that take advantage of the inherent resonance of a (quartz) crystal to obtain frequency stability.

• 一种发生高频脉冲(通常是方波)的装置,以达到同步和事件定时的目的。大多数是晶体振荡器,它利用(石英)晶体固有共振的优点,所以频率稳定。
