The bandwidth of the resonance is typically described
using the quantity
, for
quality factor.
A high-Q has a sharp resonance, and a low-Q has a
broad resonance curve.
For a vibrator set into motion and left to vibrate freely, its
decay time is proportional to the Q of its resonance.
In terms of our mechanical system, given the resistance
, the quality factor is:
