Key Points

 Q factor or quality factor is a dimensionless parameter that is used to describe the underdamped resonator and characterizes the bandwidth and center frequency of the resonator.

The bandwidth and quality factor of a series RLC circuit are both inversely related. The higher the quality factor, the lower the operating bandwidth, hence the passband is narrow.
