Owning Palette: Digital Filter Design VIs and Functions

Requires: 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 Fixed-Point Tools VIs to quantize filter coefficients, model the behavior of fixed-point multirate filters, simulate multirate filtering processes, and generate fixed-point target code.

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

Palette ObjectDescription
DFD FXP Get MRate Coef QuantizerRetrieves settings for the filter coefficients quantizer of a multirate filter.
DFD FXP Get MRate Output QuantizerRetrieves the settings for the output quantizer of a multirate filter.
DFD FXP Moving Average Code GeneratorGenerates LabVIEW field-programmable gate array (FPGA) code from a fixed-point moving average (MA) multirate filter.
DFD FXP MRate Code GeneratorGenerates LabVIEW field-programmable gate array (FPGA) code from a fixed-point multirate filter.
DFD FXP MRate ModelingCreates a fixed-point multirate filter model according to the settings of the input word length, input integer word length, and output word length.
DFD FXP MRate PostprocessingConverts the output signal of a fixed-point multirate filter from an integer, fixed-point representation to a floating-point representation. You must manually select the polymorphic instance you want to use.
DFD FXP MRate QuantizationQuantizes the coefficients of a floating-point multirate filter and generates a fixed-point multirate filter.
DFD FXP MRate SimulationSimulates the filtering process of a fixed-point multirate filter continuously. Wire data to the signal in input to determine the polymorphic instance to use or manually select the instance.
DFD FXP NStage MRate Code GeneratorGenerates LabVIEW field-programmable gate array (FPGA) code from a multistage multirate filter.
DFD FXP NStage MRate ModelingCreates a fixed-point multistage multirate filter model according to the settings of the input word length, input integer word length, and output word length.
DFD FXP NStage MRate PostprocessingConverts the output signal of a fixed-point multistage multirate filter from a fixed-point representation to a floating-point representation. You must manually select the polymorphic instance you want to use.
DFD FXP NStage MRate QuantizationQuantizes the coefficients of a floating-point multistage multirate filter and generates a fixed-point multistage multirate filter. This VI has the same internal settings as the DFD FXP MRate Quantization VI.
DFD FXP NStage MRate SimulationSimulates the filtering process of a fixed-point multistage multirate filter continuously. Wire data to the signal in input to determine the polymorphic instance to use or manually select the instance.
