Q factor
DIMENSIONLESS MEASURE FOR THE DAMPING OF AN OSCILLATOR
Quality factor; Resonance width; Quality Factor; Q-factor; Q Factor
In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. It is defined as the ratio of the initial energy stored in the resonator to the energy lost in one radian of the cycle of oscillation.
