Explain the importance of Q-Factor?

The Q-Factor indicates energy loss relative to the amount of energy stored within the system. Thus the higher the Q the lower the rate of energy loss and hence oscillations will reduce more slowly, i.e. they will have a low level of damping and they will ring for longer.

How to Calculate Q-Factor?

Q-Factor calculator uses Q Factor = 1/(2*Damping Ratio) to calculate the Q Factor, The Q-Factor formula is defined as a non-dimensional characterization of the amount of damping; high Q indicates slow damping relative to the oscillation. Q Factor is denoted by Q symbol.
