The Q or quality factor is used by experts of resonators to rate how good a resonator is. It is similar to the time constant but instead of seconds, it is a measure of the decay time (i.e. ring time) of a shock-excited resonator in terms of radians (i.e. 2π times the decay time in cycles).

2π times the decay time in cycles). This video explains how to solve a quadratic equation by factoring out the greatest common factor.Complete Video Listing: the quality factor Q alone cannot be used to infer the sample damping directly.

The first, and perhaps most common way, to define Q is given by Equation 1. 0 Average energy stored in reactive elements 2 Power dissapted by lossy elements Qf=××π [Eq 1] where f 0 is the design frequency (in which the output and input For instance, the quality factor for the damped oscillation shown in Figure 7 is. Let us find an expression for. As we have seen, the motion of a weakly damped harmonic oscillator is specified by [see Equation (72)] (81) Resonance Frequency: Quality Factor: Bandwidth: Resonant Circuit Current: Current Magnification.
