undamped natural frequency การใช้

• Where undamped natural frequency f _ 0 and Q factor are discussed above in the low-pass filter discussion.
• The damped natural frequency is less than the undamped natural frequency, but for many practical cases the damping ratio is relatively small and hence the difference is negligible.
• The frequency in this case is called the " damped natural frequency ", f _ d, and is related to the undamped natural frequency by the following formula:
