Quality Factor

The quality factor (or the Q factor) is a dimensionless parameter that describes how underdamped an oscillator or resonator is. Resonators with high quality factors have low damping, so that they oscillate longer. There are several similar, but not identical definitions of the quality factor, which become approximately equivalent in the limit of higher Q factor values.
