Hi River,

You can find it in Signal Processing-> Filters -> Butterworth in LabVIEW functions.

Thanks,

how about feeding your filter with a delta waveform (...,0,0,0,1,0,0,0,...) ?

Do not make it more complicated than it is. Go to help in the toolbar. Select "Find Example" then search for filter and loacte the "IIR Filtering and Response.vi"
