This file contains important information about the LabVIEW 2014 Digital Filter Design Toolkit, including installation instructions, new features, and known issues.
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:
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:
You can apply the adaptive filter that you create to applications like adaptive noise cancellation, adaptive echo cancellation, system identification, and so on. You also can create and implement a fixed-point adaptive filter on NI FPGA targets.
In addition to the graphical tools for digital filter design, the toolkit also provides Digital Filter Design MathScript RT Module functions that LabVIEW MathScript supports. These functions enable you to design filters in a text-based environment. You must install the LabVIEW MathScript RT Module to use the Digital Filter Design MathScript RT Module functions.
In addition to the system requirements for the LabVIEW Development System, the Digital Filter Design Toolkit has the following requirements:
Refer to the LabVIEW Readme for additional system requirements and supported operating systems for LabVIEW 2014.
Note If you want to use the Digital Filter Design Toolkit to generate LabVIEW FPGA code for a fixed-point digital filter, you must install the LabVIEW FPGA Module and NI-RIO software on the host computer. Ensure that you install the FPGA Module and NI-RIO software before you install the Digital Filter Design Toolkit. If you already installed the Digital Filter Design Toolkit, uninstall the Digital Filter Design Toolkit before installing the FPGA Module and NI-RIO software.
You can install all of your LabVIEW products—including the Digital Filter Design Toolkit—using the LabVIEW 2014 Platform media. Refer to the LabVIEW Installation Guide on the LabVIEW Platform media for installation instructions and system requirements.
To request additional LabVIEW Platform media, refer to the National Instruments 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.

The Digital Filter Design Toolkit 2014 provides Adaptive Filter VIs for you to design floating-point and fixed-point adaptive filters for different applications and with different adaptive filter algorithms.
You can access the software and documentation known issues list online. Refer to the National Instruments website for an up-to-date list of known issues in the Digital Filter Design Toolkit.
Refer to the LabVIEW Help, accessible from Help»LabVIEW Help, for information about the Digital Filter Design Toolkit.
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 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.
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 automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes. However, starting with the August 2012 releases (products using NI Installers version 3.1 or later), you may need to perform additional steps before or during a silent installation of NI software.
If the NI product you are installing uses Microsoft .NET 4.0, 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 4.0 separately before you install NI software.
For more information about automating the installation of NI products, refer to the following KnowledgeBase articles:
When you install National Instruments software on Microsoft Windows 8.x, you will notice a few additional tiles in the Apps view, including shortcuts to NI application software products such as NI LabVIEW, Measurement & Automation Explorer (NI MAX), and NI Launcher.
NI Launcher helps you find and launch installed NI products. It provides you with a method of finding NI products similar to the Start menu in previous versions of Microsoft Windows. To use NI Launcher, click the NI Launcher tile in the Apps view. NI Launcher launches the desktop and opens a menu containing a list of NI products. Click any NI product to launch it.
|Note NI MAX does not appear as a desktop shortcut when installed on Microsoft Windows 8.x. You can launch NI MAX either from the Apps view or from within NI Launcher.|
For convenience, you can pin your most-used NI applications, such as MAX, to either the Start screen or the Taskbar on the desktop, as necessary:
|Current Application||Icon Location||Pin to Action|
|Windows 8.x Desktop||Desktop Taskbar||Right-click application and select Pin to Taskbar|
|Windows 8.x Desktop||Start screen||Right-click application and select Pin to Start|
|Windows 8.x Start screen||Desktop Taskbar||Right-click application and select Pin to taskbar from the menu bar on the bottom of the screen|
If you want to find a particular application or related files, such as documentation files, from the Start screen, you can access all installed files from the Apps view. To get to the Apps view, right-click anywhere on the Start screen and select All apps (Windows 8) or click the down arrow on the bottom left of the screen (Windows 8.1).
For more information about NI support for Windows 8.x, visit ni.com/windows8.
National Instruments LabVIEW Digital Filter Design Toolkit will drop support for Microsoft Windows Vista, Windows XP, and Windows Server 2003 as of July 1, 2016. Versions of the Digital Filter Design Toolkit that ship after July 1, 2016 will not install or run on Windows Vista, Windows XP, or Windows Server 2003.
