Overview

The Digital Filter Design Toolkit includes the Digital Filter Design VIs and the Adaptive Filters VIs to provide a collection of digital filter design tools, including adaptive filter design tools, to supplement the LabVIEW Full Development System. The Digital Filter Design Toolkit helps you design digital filters and filter banks without requiring you to have advanced knowledge of digital signal processing or digital filtering techniques. With the Digital Filter Design Toolkit, you can design and analyze floating-point and fixed-point digital filters and filter banks. With the Digital Filter Design Toolkit, you also can design and analyze floating-point and fixed-point adaptive filters. You also can simulate fixed-point digital filters, including fixed-point adaptive filters.

Without prior knowledge about programming in LabVIEW, you can use the Digital Filter Design Express VIs to interact graphically with filter specifications to design appropriate digital filters and filter banks.

The Digital Filter Design VIs help you design the following filters and filter banks:

• Digital finite impulse response (FIR) or infinite impulse response (IIR) filters—You can use the VIs to analyze the characteristics of the digital filter, change the implementation structure of the digital filter, and process data with the digital filter. In addition to the floating-point support, the Digital Filter Design VIs also help you create a fixed-point digital filter model, analyze the characteristics of the fixed-point digital filter, simulate the performance of the fixed-point digital filter, and generate fixed-point C code, or integer LabVIEW code.
• Floating-point multirate digital filters—You can use the VIs to design a floating-point single-stage or multistage multirate filter, analyze the characteristics of the floating-point multirate filter, and process data with the floating-point multirate filter. In addition to the floating-point filter design, the Digital Filter Design VIs also help you create a fixed-point multirate filter, analyze the characteristics of the fixed-point multirate filter, and simulate the behavior of the fixed-point multirate filter.
• Filter banks—You can use the VIs to design a 2-band quadrature mirror filter (QMF) or M-band cosine-modulated filter bank, analyze the characteristics of a filter bank, decompose or reconstruct signals with filter banks, retrieve filter bank parameters, and create a filter bank from a prototype filter.
  

The Adaptive Filters VIs help you design a floating-point and fixed-point adaptive filter for different applications and with different adaptive filter algorithms. You can use the Adaptive Filters VIs to create an adaptive filter with the following adaptive algorithms:

• Least mean squares (LMS) and the variants, such as normalized LMS, leaky LMS, normalized leaky LMS, sign LMS, and fast block LMS
• Filtered-x LMS and normalized filtered-x LMS
• Recursive least squares (RLS) and QR decomposition-based RLS (QR-RLS)
  

You can apply the adaptive filter that you create to applications like adaptive noise cancellation, adaptive echo cancellation, and system identification.

In addition to the graphical tools for digital filter design, the toolkit also provides Digital Filter Design MathScript Module functions that LabVIEW MathScript supports. These functions enable you to design filters in a text-based environment. You must install the LabVIEW MathScript Module to use the Digital Filter Design MathScript Module functions.

System Requirements

In addition to the system requirements for the LabVIEW Development System, the Digital Filter Design Toolkit has the following requirements:

• LabVIEW 2021 Full or Professional Development System
• At least 200 MB of disk space
  

Refer to the LabVIEW Readme for additional system requirements and supported operating systems for LabVIEW.

Supported Operating Systems

The Digital Filter Design Toolkit supports the following operating systems:

• Windows 10
• Windows Server 2019
• Windows Server 2016
  

Note  Refer to Unsupported Windows Operating Systems for more information about support for Microsoft Windows OSes.

Installation Instructions

Download the Digital Filter Design Toolkit installer from ni.com/downloads. NI software includes NI Package Manager to handle the installation. Refer to the NI Package Manager Manual for more information about installing, removing, and upgrading NI software using Package Manager.

You can also install LabVIEW and the Digital Filter Design Toolkit by using the LabVIEW Platform media. To request additional LabVIEW Platform media, refer to the NI website.

Note  If you purchased this product with an NI Software Suite or NI Product Bundle, use the installation media that shipped with your purchase to install this product.

Product Security and Critical Updates

Visit ni.com/security to view and subscribe to receive security notifications about NI products. For information about critical updates from NI, refer to Available Critical and Security Updates for NI Software.

Accessing the Help

Refer to the LabVIEW Help, accessible from Help»LabVIEW Help from LabVIEW, for information about the Digital Filter Design Toolkit.

Finding Examples

Select Help»Find Examples from LabVIEW to launch the NI Example Finder. Navigate to the Toolkits and Modules»Digital Filter Design folder and the Toolkits and Modules»Adaptive Filters folder to access the examples. You also can find the examples for the Digital Filter Design Toolkit in the labview\examples\Digital Filter Design directory and the labview\examples\Adaptive Filters directory. You can modify an example VI to fit an application, or you can copy and paste from one or more examples into a VI that you create.

Automating the Installation of NI Products

You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes.

If the NI product you are installing uses Microsoft .NET 4.6.2, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.6.2 separately before you install NI software.

For more information about automating the installation of NI products, refer to Automating an Installer in the NI Package Manager manual.

Using NI Software with Microsoft Windows 10

Microsoft Windows 10 is the latest version of the Windows operating system and features significant changes compared to previous versions. Windows 10 introduces several new capabilities and also combines features from both Windows 7 and Windows 8. For more information about NI support for Windows 10, visit ni.com/windows10.

Unsupported Windows Operating Systems

The Digital Filter Design Toolkit no longer supports Windows Vista/XP/7/8.x, Windows Server 2003/2008/2012, or any 32-bit Windows operating system. Versions of this product that ship after May 1, 2021, may not install or execute correctly on these operating systems.
