Hi
I was wondering if any body knows how I can handle the problem of edge effect caused by zero phase filtering? The problem is that by using zero phase filtering if the intial condition of forward filter does not equal to that of reverse filter, a kind of spike will occur at the begining and the end of filtered signal. In MATLAB spacial care has been taken to minimize this effect but it seems it is not the case in LabView?
I noticed that some body mentioned the same problem here long time ago and one of replies pointed out that it is the transient effect of convolution and we need to remove the first and last samples of filtered signal but I don't think that it is a wise solution because the problem is not because of convolution.
Best regards
Afshin
