  • Smoothing Data

    Dear Biomch-l'ers:

    We are currently using an Electromagnetic tracking device to collect
    about 1200 data points. (linear in time)

    We wish to use LabVIEW 3.1.1 to analyze these outputs.

    Currently, the data is "noisy" and needs to be filtered or smoothed
    in some way. Our difficulty is that with certain filters,
    specifically the Butterworth filter, there
    are edge effects that distort the data until the filter settles down.

    For our specific application, this is unacceptable.

    Does there exist a low-pass filter that can interpret edge effects
    better?

    Or alternatively, (even preferably) is there a "smoothing" function which
    would be able to "smooth out" our data?

    Thanks in advance.

    Dave.
