Q and Bandwidth
In the above circuit
The inductors reactance at this resonance frequency is
- Bandwith
- The most common definition for the Bandwidth of this circuit is the frequency range over which the output decreases by 3 dB. This correspond to the frequency at which the circuits power is cut in half from the resonance frequency.
- Quality Factor
- The Quality factor for this circuit may be expressed in term of the bandwidth such that
