    Could someone please explain what it would mean to pass data through a 3 second 1st order filter? Any help is appreciated, thanks!

    You are not going to get any answers because I doubt that there is anyone that understands the question. You are lacking significant amount of information.

    1) What is the data?
    2) What is the significance of "3 second"?
    3) What type of filter is the "1st order filter", low-pass, high-pass, band-pass, band-stop, notch?
    4) What is the cut-off frequency of the filter?

    If by "3 second" you mean a time-constant of 3 seconds then the filter corner frequency would be 0.05Hz. As MrChips noted what that does to the data depends upon the data and the type of 1st order filter it is.

    Do you need some introduction to filtering. I can see what I can come up with from the web. For a beginner it can be hard to know what to look for
