human vibration frequency weightings

[neilm]

Sound and vibration toolset includes audio weighting filters (A, B, C etc). I need human vibration filters, Wk, Wd, Wb, Wh etc to apply in the time domain to raw acceleration signals. I have the parameters required to specify the filters in the s-plane. They are broken up into high and low pass butterworth (I can cope with that) but I don't know where to start for the 'a-v transition' and 'upward step'. Any tips would be gratefully received!

Thanks a lot for the help,

Neil.

I'm not sure about the a-v transition or upward step but you could use either the fourier transform or inverse fourier transform VIs to get your signals in the same domain.
