Quality Factor

The Quality Factor, often abbreviated as Q-factor, is a measure used to describe how well a system can resonate or oscillate. In simpler terms, it indicates the efficiency and selectivity of something, like an audio speaker or a mechanical system. A high Q-factor means the system can sustain vibrations longer without losing energy, resulting in clearer sounds or more precise movements. Conversely, a low Q-factor indicates more energy loss and less efficient performance. Overall, it helps assess the balance between energy stored and energy lost in various applications, from electronics to engineering.
