Quality Factor

Let us review the many definitions of the quality factor, $Q$. 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:

$H\left(j\omega \right)={\frac {1}{R\left(\omega \right)+jX\left(\omega \right)}}$

We can define the component quality factor as:
