FIR

[pietrovl1]

Hi to all… For my job of thesis I am using a CompactRio with which I must acquire of marks them in order then to be able to carry out on they several measures. They are successful to implement in LabView a VI with which I acquire on eight channels. Mine marks them can be subject to of disturbs, therefore I carry out a filtering FIR, through a subVi, in order to eliminate such disturbance. Hour but filter FIR carries out one medium weighed  on a window of N champions of data. First K (order of the filter) exited of the filter is wrong, because the filter has still not gone to regimen; therefore first K champions will go lost after that  would begin to having the exact escapes. This in the first cycle of acquisition; subsequently I would have to proceed always in the same way always wasting first K champions in order to wait for that the filter goes to regimen! Instead I would want to use K previous champions as conditions begin them in order to obtain exited K successive and to make to work the filter in continuous way at the beginnig, obtaining exited K wrong of the first cycle of acquisition and subsequently exited always corrected. I am from some week but nn I have still found the solution… someone can give to me one hand? 

If you want I can also send my files .

thank you…

Hi,

I'd like to give you some useful indications but I haven't understood what you want to realize.

Could you clarify your problem?
