On my textbook, there are several definition given for this Q factor.
1) 2 pi * maximum energy stored in reactive element / energy dissipated in a period
2)resonance frequency (in terms of ω) / band width
3)Q = 1/(2 * damping factor)I have tried a couple of random circuits, and its seems not all of them are correct for arbitrary circuit. (Some o them may only true for simple RLC series of parallel).
May I ask which statement is always true?
My textbook also says resonant frequency = natural frequency *(1-2*zeta^2) where zeta is damping factor
and undamped natural frequency is = natural frequency *(1-*zeta^2) where zeta is damping factor
Are these true for RLC series only??
Thank you!
