Finite Impulse Response filters have --
Wow, A Finite Response -ooh. So, they will need to collect and process the input data in (well, a "Finite" manner!)
Those finite (Known) parameters may be Known! See CA for that!
Now, can you give data inputs and desired outputs?
Sad that nobody spent 2 minutes to look in the palettes. It took me less than 30 seconds to find this VI in the Signal Processing->Filters palette: Zero Phase Filter VI. It looks like it behaves exactly like that Matlab function.
Thanks. I am already aware of the zero phase filter vi ( I actually hoped some of the first responders would have atleast mentioned that and then more :))
I guess what I need to know is how to generate and feed in the forward and reverse co-efficients to the zero phase filter vi. Possibly from the outputs of an FiR filter. I am not sure the MATLAb function is just a zero phase filter function. It looks like zero phase filtering done after applying an FIR filter. I also observed that labVIEW seems to have edge effects here the first one or two points greatly differ from the original function ( similarly the last two points)
