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, integer LabVIEW code, or (32-bit only) LabVIEW field-programmable gate array (FPGA) code for NI FPGA targets.
• 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, simulate the behavior of the fixed-point multirate filter, and (32-bit only) generate LabVIEW FPGA code from the fixed-point multirate filter for FPGA targets.
• 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. (32-bit only) You also can create and implement a fixed-point adaptive filter on FPGA targets.

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 2019 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 2019.

Note  (32-bit only) 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.

Supported Operating Systems

The Digital Filter Design Toolkit supports the following operating systems:

• Windows 10 (version 1809)/8.1 Update 11/7 SP12
• Windows Server 2012 R21
• Windows Server 2008 R2 SP12
  

1 NI software installs VC2015 Runtime and .NET 4.6.2. Windows 8.1 and Windows Server 2012 R2 require Microsoft updates to support these items. Refer to Microsoft KB2919442 and KB2919355 for more information about how to install these updates.

2 NI software is signed with a SHA-256 certificate. Windows 7 SP1, Windows Embedded Standard 7 SP1, and Windows Server 2008 R2 SP1 require Microsoft updates to support SHA-256. Refer to Microsoft KB3033929 for more information about how to install this security update.
