Overview

The LabVIEW 2010 Digital Filter Design Toolkit is the upgrade version of the LabVIEW 2009 Digital Filter Design Toolkit. The Digital Filter Design Toolkit provides a collection of digital 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. You also can simulate fixed-point digital 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 Toolkit provides VIs that you can use to design a digital finite impulse response (FIR) or infinite impulse response (IIR) filter, 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 Toolkit provides a set of VIs that you can use to 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 LabVIEW field-programmable gate array (FPGA) code for a specific fixed-point target.

The Digital Filter Design Toolkit includes VIs for floating-point multirate digital filter design. 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 toolkit also provides a set of VIs that you can use to 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 generate LabVIEW FPGA code from the fixed-point multirate filter for NI-RIO targets.

The Digital Filter Design Toolkit includes VIs that you can use to design and analyze 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.

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.

New Features and Changes

• Use the LabVIEW 2010 Digital Filter Design Toolkit to design and analyze filter banks. Filter banks are arrays of bandpass filters that separate an input signal into several components, each of which carries a single frequency subband. You can perform signal processing on the separated components individually.
• The DFD Plot Freq Response VI can plot the frequency responses of a filter using logarithmic-spaced and frequency vector methods. Use the plot settings and frequency vector inputs to specify the number of frequency bins and the frequency range this VI plots in the frequency response.
• The DFD Windowed FIR Design VI can create an FIR filter using the Kaiser, Dolph-Chebyshev, and Gaussian window methods. This VI contains the window parameter input. Use the window parameter input to specify the beta parameter for a Kaiser window, the standard deviation for a Gaussian window, and the ratio of the mainlobe to the sidelobe for a Dolph-Chebyshev window.
• The File I/O VIs are now on the File I/O palette. You can use the File I/O VIs to save/retrieve a filter bank to/from a file or text file.
• You can use the More Options and Throughput Configuration dialog boxes to specify additional settings for the LabVIEW FPGA code you generate for single-rate, multirate, and multistage multirate FIR filters.
  

System Requirements

The computer you are using must meet the following minimum system requirements to run the Digital Filter Design Toolkit:

• 120 MB free disk space
• LabVIEW 2010 Full or Professional Development System
  

Note: If you want to use the LabVIEW 2010 Digital Filter Design Toolkit to generate LabVIEW FPGA code for a fixed-point digital filter, you must install the LabVIEW 2010 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 run the Digital Filter Design Toolkit on the following operating systems:

• Windows 7 (32-bit and 64-bit)
• Windows Vista (32-bit and 64-bit)
• Windows XP (32-bit)
• Windows Server 2003 R2 (32-bit)
• Windows Server 2008 R2 (64-bit)
  

Note: The Digital Filter Design Toolkit does not support Windows NT/Me/2000/98/95 or the Windows Server non-R2 editions.
