Critical DampingCritical damping provides the quickest approach to zero amplitude for a damped oscillator. With less damping (underdamping) it reaches the zero position more quickly, but oscillates around it. With more damping (overdamping), the approach to zero is slower. Critical damping occurs when the damping coefficient is equal to the undamped resonant frequency of the oscillator.

Overdamped OscillatorOverdamping of a damped oscillator will cause it to approach zero amplitude more slowly than for the case of critical damping. The damping coefficient is greater than the undamped resonant frequency .
