Signals and Systems/Second Order Transfer Function

WebThe factor is known as Q ( quality factor ). The higher the Q, the better the filter; the lower the losses, the closer the filter is to being perfect. Although Q may be defined in several ways, a general definition that applies to any system is based on the ratio of the energy stored in the system to the energy dissipated per cycle: The Q factor determines the qualitative behavior of simple damped oscillators. (For mathematical details about these systems and their behavior see harmonic oscillator and linear time invariant (LTI) system.) • A system with low quality factor (Q < 1⁄2) is said to be overdamped. Such a system doesn't oscillate at all, but when displaced from its equilibrium steady-state output it returns to it by expo…
