Is it possible to build Octave filter in LV?

[Navne]

Hello masterminds

I have a request for an noise measurement application being able to filter around a few select frequencies at 1 / oct bandwith. 

I know this is available in the sound and vibration tool kit, but adding such an expensive suite of tools to the project is not feasible for such a small feature.

I'm not a filtering guru. Is there anyone here who can point me in the direction of how to implement a simple filter with 1 oct bandwidth at a fixed frequency? Thank you in advance. 

Environment is LV 2012 on windows.

In the signal processing palette there is a butterworth filter.  Just set it to type bandpass and pass it a high frequency of 1.414 * center frequency and a low frequency of 0.707* center frequency.

You can try the other filter types tchebyshev etc if you want to play around with different phase responses.
