Designing a digital filter

After determing the natural frequency of a beam, I am tasked to design a digital filter to retain this frequency (filter out all other frequencies). How do I go about this process?

With the Signal Processing Toolbox, use the bandpass function. For best results, use the 'ImpulseResponse','iir' name-value pair. This will design a very efficient elliptic bandpass filter.

If you need to do it from command-line arguments, that is straightforward. I will post that if you request it.
