The Q factor determines the qualitative behavior of simple damped oscillators. (For mathematical details about these systems and their behavior see harmonic oscillator and linear time invariant (LTI) system.) • A system with low quality factor (Q < 1⁄2) is said to be overdamped. Such a system doesn't oscillate at all, but when displaced from its equilibrium steady-state output it returns to it by expo… http://www.maglev.ir/eng/documents/papers/conferences/maglev2002/topic8/IMT_CP_M2002_T8_S2_1.pdf

WebTo calculate the damping factor with a real cable, of a given length and thickness (gauge), between the amplifier and the load (the loudspeaker), we have to add an additional term to the above formula: the impedance of the cable. Web• The damping factor of a system is the ratio of the loudspeaker's nominal impedance to the total impedance driving it • Example: Amplifier with damping factor of 300 (bigger is better) driving an 8 Ωload means that the output • Impedance of speaker cable used can significantly reduce the damping factor (larger gauge wire has lower how to spell the name shamus
