WebTo avoid the particle problem, the manufacturers of quartz crystals have conventionally taken the oscillation margin more than fivefold in the products for the general consumer market and more than tenfold in the products for the automotive onboard electronic equipment market. The Q factor determines the qualitative behavior of simple damped oscillators. (For mathematical details about these systems and their behavior see harmonic oscillator and linear time invariant (LTI) system.) • A system with low quality factor (Q < 1⁄2) is said to be overdamped. Such a system doesn't oscillate at all, but when displaced from its equilibrium steady-state output it returns to it by expo…
