Stan Yes Arild Danielson of Norway coded a very useful set of Savitsky-Golay filtering functions. He made them publically available in February 1997. They still work fine in LV7, although the originals were in LV4.1 I believe. The VI llb which contains all necessary VIs and also a nice demo to compare the Savitzky-Golay with other more conventional means of filtering is called Firfunc.llb. This library should be found in info-labview archives.
The author gets all the credits for this very nice and useful suite of VIs. Arild are you still listening somewhere on this planet? I hope you can get them from the archives or directly from the author.
