Thanks for the response Joel. So if I understand correctly, Q is
basically an indicator of how well the LC circuit resonates? Could you
think of Q as the inverse of a dampening coefficient?
Just about exactly. You'll find the term "damping factor" (sometimes
"damping ratio" or "damping coefficient") often used in many situations
involving network analysis and control systems, usually represented by
the lowercase Greek letter zeta. And it's numerically equal to 1/(2Q),
so Q is exactly 1/2 the inverse of the damping factor.
When the damping factor is 1 (Q = 0.5), a second order circuit is said
to be critically damped.
