A correction to my previous comment. Linear or Spline interpolation is
not the way to go if you wish to decimate your data. The correct
technique is, as you mention, to filter your signal before data
decimation (dropping samples).
You are considering to use a Bessel filter. I assume this is becaus
LabVIEW 6.1 offers some few resampling options with the low level VIs.
(Linear and Spline interpolation). See for example the VI attached to

How can i do re-sampling in LabVIEW 6.1?
