Crystals

Crystals.jpg
Crystals, in the context of electronics, refer to quartz crystals or other similar crystalline structures used as precise timing references or frequency-determining elements. These crystals exhibit a phenomenon called piezoelectricity, which allows them to generate a stable and accurate electrical signal when subjected to mechanical stress or voltage. Crystals are extensively used in oscillators
