NATIONAL Instruments has released the NI LabVIEW Digital Filter Design Toolkit Version 7.5. It includes tools for modelling and creating software-based digital filters as well as LabVIEW FPGA and C code generation capabilities for chip-level implementation.
Design and test engineers can use the NI LabVIEW graphical development environment to ensure a seamless digital filter design process from conception to completion while reducing development costs. Professors can use the toolkit to demonstrate filter design concepts to undergraduate and graduate engineering students.
To efficiently design a digital filter, engineers rely on a variety of software tools for iterative design, optimisation and implementation. The toolkit provides a single software tool that engineers can use throughout the process to quickly and interactively design custom floating- or fixed-point filters for tasks such as noise reduction, signal extraction, anti-aliasing and resampling. The toolkit includes four new Express VIs for interactive configuration and offers a wide range of standard digital filter design algorithms for fine-tuning specifications.
Engineers without significant signal processing experience can access nearly 80 example VIs to help them get started. The toolkit also has algorithms such as the Remez exchange method and the least Pth norm method for applications including telecommunications and electronics design.
The LabVIEW Digital Filter Design Toolkit includes tools for implementing newly designed filters on both floating and fixed-point targets. Users can generate ANSI C code for deployment on DSP chips and LabVIEW FPGA code for implementation on NI FPGA devices including PXI and PCI plug-in devices and NI CompactRIO embedded systems.
