correlation in labview

[LSASS]

Heya People!

I am new to labview, and would really like some help understanding the cross-correlation VI. Why do they have a biased normalisation input? what is the purpose of it?

And what does unbiased normalisation mean? The labview help is just so confusing, and I don't understand what they mean properly.

Thanks a lot  for your help:)

Hello,

It will depend on the data you have whether or not you need to normalize to get a more accurate comparison of the two sets. Have you seen the equations for biased and unbiased normalization? They are in the LabVIEW help in the Details section at the bottom. This section explains what normalization formula is implemented. The point of normalization is to divide out a common variable to negate its effect on the data and this allows you to better compare data of different scales.
