Owning Palette: Digital Filter Design VIs and Functions

Use the Multirate Utilities VIs to retrieve the multirate filter coefficients and parameters and to create multirate filters from the filter coefficients.

The VIs on this palette can return general LabVIEW error codes or specific digital filter design error codes.

Palette Object	Description
DFD Build CIC Filter	Creates a cascaded integrator comb (CIC) filter.
DFD Build MRate Filter	Creates a multirate filter. You must manually select the polymorphic instance you want to use.
DFD Get MRate CIC Parameters	Retrieves the transfer function coefficients, sampling frequency conversion factor, filtering mode, and filter parameters of a cascaded integrator comb (CIC) filter.
DFD Get MRate Filter Parameters	Retrieves the transfer function, sampling frequency conversion factor, and filtering mode of a multirate filter.
DFD Get MRate Filter Structure	Retrieves the structure of a multirate filter. A multirate filter can have either a finite impulse response (FIR) or cascaded integrator comb (CIC) structure.
DFD Load from File	Retrieves a filter from a file. You must manually select the polymorphic instance you want to use.
DFD Save MRate to Text File	Saves a multirate filter to a text file in XML format.
DFD Save to File	Saves a filter into a file. The data type you wire to the filter in input determines the polymorphic instance to use. Use the DFD Load from File VI to load the filter from the file.
