National Instruments has announced the latest version of the NI LabVIEW Digital Filter Design Toolkit, for designing and implementing digital filters.

The toolkit features text-based MathScript functions for advanced filter design, and there is support for multi-rate filter design and implementation and enhanced fixed-point code generation.

Engineers can use the new design tools for floating-point and fixed-point multi-rate filters for decimation, interpolation and rational re-sampling with fixed-point code generation capability.

Multi-rate filters are useful for connecting components of DSP systems that operate at different sample rates. The latest version of the Filter Design toolkit offers enhanced code generation capability with better use of FPGA resources, which the firm said makes it possible for filters to share coefficients and control resources among multiple channels.

For fixed-point designs, engineers can also model quantisation effects and automatically generate ANSI C and LabVIEW FPGA code for deployment on FPGAs, DSPs or other embedded targets.
