Multirate Utilities VIs
Owning Palette: Digital Filter Design VIs and Functions
Installed With: Digital Filter Design Toolkit. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
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. Wire data to the filter in input to determine the polymorphic instance to use or manually select the instance. Use the DFD Load from File VI to load the filter from the file. |
