NI Digital Filter Design Toolkit for LabVIEW

The National Instruments Digital Filter Design Toolkit extends LabVIEW with functions and interactive tools for design, analysis, and implementation of digital filters.

If you are new to digital filters, you can use interactive design tools to rapidly explore classical designs; if you are experienced with digital filters, you can use a breadth of algorithms, filter topologies, and analysis tools for design, modeling, and implementation of both fixed- and floating-point digital filters.

An extensive set of examples can serve as starting points for your floating- or fixed-point designs. For fixed-point filters, you can model quantization effects and automatically generate ANSI C and LabVIEW FPGA code for digital signal processor (DSP) or FPGA deployment.

System Requirements

The Digital Filter Design Toolkit Version 8.20:

• Supports Windows 2000/XP
• Requires National Instruments LabVIEW 8.20 (or later), full or professional edition

To implement fixed-point filter designs, the Digital Filter Design Toolkit can automatically generate ANSI C code, integer LabVIEW code, and Single-Cycle Timed Loop (SCTL) LabVIEW FPGA code. The generated C code can be compiled on any ANSI-compliant C compiler such as National Instruments LabWindows/CVI. The LabVIEW FPGA code requires the LabVIEW FPGA Module and a suitable LabVIEW FPGA target platform.
