IS there a way to eliminate noise or smooth data aquired from an SCXI-1000?

[Joseph Jankowski]

I am running an AT-MIO-16E-1 with an SCXI-1000 and an SCXI 1120 card. The data that I aquire from this is full of noise, but well within the specifications from NI. I am sampling at 5000S/s and was wondering if I could write a component into the Labview Interface that would smooth this data or provide me a trend of the data eliminating this noise. For some reason, and I believe it is in the software, this 15 year old macintosh yields better data and I believe that there is some smoothing routine in the Labview 2.0 fucntions that it uses. If you have any suggestions, please recommend the names of the componets that I would need to wire in, and I will read up on how to do it. If you would like
I could supply the code that I am using too.

Thanks,

Joe

One good way of doing this is with a Waveform Average vi. I believe there's one in the NI code exchange archives. This works with any array or waveform.

Joe,
Here are some links that discuss digital filtering in LabVIEW. I just did a search on the web site for "labview digital filter".
How Do I Select the Correct Filter in LabVIEW for My Application?
Reducing Noise Using Digital Filtering in LabVIEW


In addition LabVIEW 7.0 has an express VI that does filtering of signals.
