Electronics (DoD): Characteristics of Crystals
Characteristics of Crystals
This video stresses the importance of frequency stability and introduces the crystal controlled oscillator as a possible device used to obtain this stability. It also explains the piezoelectric effect of a crystal, lists types of crystals having the piezoelectric effect, and points out the relationship between crystal thickness and frequency. Various crystal cuts are explained and shown graphically. The q of the crystal circuit is explained, and both the physical dimensions and electrical characteristics of a typical crystal are discussed.
