Owning Palette: Digital Filter Design VIs and Functions

Use the Fixed-Point Tools VIs to quantize coefficients, model the behavior of fixed-point filters, simulate filtering processes, generate statistics reports, 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 Object	Description
DFD Convert FXP to Integer	Converts fixed-point numbers to integers. You must manually select the polymorphic instance you want to use.
DFD Convert Integer to FXP	Converts integers to fixed-point numbers. The data type you wire to the I16 input determines the polymorphic instance to use.
DFD FXP Code Generator	Generates fixed-point code from a fixed-point filter, including fixed-point LabVIEW FPGA code, integer LabVIEW code, and C code. You must manually select the polymorphic instance you want to use.
DFD FXP Coef Report	Generates a text report about the coefficients of a fixed-point filter.
DFD FXP Get Quantizer	Retrieves quantizer settings from a fixed-point filter. You must manually select the polymorphic instance you want to use.
DFD FXP Modeling	Creates a fixed-point filter model according to the input and output word length settings.
DFD FXP Postprocessing	Converts the output signal of a fixed-point filter from a fixed-point integer representation to a floating-point representation. You must manually select the polymorphic instance you want to use.
DFD FXP Quantize Coef	Quantizes the coefficients of a floating-point filter and generates a fixed-point filter. You must manually select the polymorphic instance you want to use.
DFD FXP Set Quantizer	Sets a quantizer or quantizers in a fixed-point filter. You must manually select the polymorphic instance you want to use.
DFD FXP Simulation Report	Creates a text report of filtering statistics from the DFD FXP Simulation VI or the DFD FXP Simulation with State VI.
DFD FXP Simulation with State	Simulates the filtering process with initial internal states and generates the filtering statistics report for a fixed-point filter. The data type you wire to the signal in input determines the polymorphic instance to use.
DFD FXP Simulation	Simulates the filtering process continuously and generates a filtering statistics report for a fixed-point filter. The data type you wire to the signal in input determines the polymorphic instance to use.
