The Designing Special Filters book discusses linear phase finite impulse response (FIR) filter designs, which are actually amplitude approximations that use the following complex approximation criterion: ...

You usually program target digital signal processing (DSP) hardware using C code. To generate C code from the fixed-point filter model, use the C Code instance of the DFD FXP Code Generator VI. You can ...

Integer LabVIEW code can run on any platform or target on which you can run LabVIEW VIs. Integer LabVIEW code is useful when you simulate the behavior of a fixed-point filter on Windows. You can use the ...

LabVIEW field-programmable gate array (FPGA) code is a type of code specifically optimized to run on NI Reconfigurable I/O (RIO) devices such as the NI PXI-7831R. LabVIEW FPGA code takes advantage of the ...

Infinite impulse response (IIR) filters that you design using Butterworth, Chebyshev, or Elliptic methods usually have a nonconstant group delay, which means that they have nonlinear phase or phase distortion. ...

Fixed-point numbers can represent only numbers of a finite range. Overflows occur when a number is greater than the maximum representable number within the range. Underflows occur when a number is less ...
