Damped Natural Frequency

</dt>
The frequency of free vibration of a damped linear system. </dd>
The oscillation of a damped system may be considered periodic in the limited sense that the time interval between zero crossings in the same direction is constant if the system is linear, even though successive amplitudes decrease progressively. The frequency of the oscillation is the reciprocal of this time interval. The damped natural frequency decreases as the damping increases, and approaches zero as the damping approaches critical damping. [[/a>|/a>]] </dd>
