Let us review the many definitions of the quality factor, . This context-dependent metric can allow us to gain important insights on the behavior and implementation of energy storage and loss in circuits.

Component Quality Factor

For a transfer function that we can write as:

 

 

 

 

(1)

We can define the component quality factor as:

 

 

 

 

(1)

Pole Quality Factor

Band-Pass Filter Quality Factor
