Dissipation factor
Measure of loss-rate of energy of a mode of oscillation in a dissipative system / From Wikipedia, the free encyclopedia
In physics, the dissipation factor (DF) is a measure of loss-rate of energy of a mode of oscillation (mechanical, electrical, or electromechanical) in a dissipative system. It is the reciprocal of quality factor, which represents the "quality" or durability of oscillation.
