Q Angle of the Knee. The Q angle of the knee is a measurement of the angle between the quadriceps muscles and the patella tendon and provides useful information about the alignment of the knee joint.
Chapter 6 - Resonance. The Q, quality factor, of a resonant circuit is a measure of the âgoodnessâ or quality of a resonant circuit. A higher value for this figure of merit corresponds to a more narrow bandwith, which is desirable in many applications. More formally, Q is the ratio of power stored to power dissipated in the circuit reactance and resistance, respectively:
