Filter Design Problems - Labview 8.2

[alanb]

I am trying to designe a filter to replicate the frequency weighting curves in ISO-2631-4.

These curves are specified (in third octace steps) between 0.1 and 400 hz

I have based my design on the "DFD least Pth Norm Design.vi"

I have created the band specification array but in my vi I do not appear to be getting anthing out of the "DFD Get Freq responce.vi"

Any thoughts

I quite new to filter design,  Am I using the right technique? If not how should I be implementing this filter?

Attached is my vi

Thanks
