To understand what FIR filters are and do I would search the web for digital signal processing basics.
In practical use you will have to make a choice between using IIR of FIR.
In FIR you add a number of delay-lines with gain-factors. In IIR you do the same but feed-back is added. Generally IIR takes less processing compared to FIR, but is less "ideal".

Hello,
Depending on what you would like to do with FIR filters, LabVIEW has different filter VIs, such as FIR Filter Design, FIR Windowed Filter, FIR Narrowband Filter...
Refer to the examples\analysis\fltrxmpl.llb for an example of using the Filter VIs.

There are a few useful pages on NI Developer Zone:

The link above has a link "digital filter" that has some useful information. There are also LabVIEW Player examples that illustrate many signal processing concepts through code you can run:

If you search on ni.com/zone for digital filter you should find some more documents.

Best of luck,
