LabVIEW Digital Filter Design Toolkit Overview

This user manual contains information about the general design process and the tools in the Digital Filter Design Toolkit that you can use in a digital filter or filter bank design. This user manual also contains information about the general process and the tools in the Digital Filter Design Toolkit that you can use in an adaptive filter for different applications and with different adaptive filter algorithms.
Note Filters in this user manual refer to single-rate filters unless a section specifies the use of multirate filters.

You can use the Signal Processing VIs in the LabVIEW Full or Professional Development System to perform the following tasks:

  • waveform measurements
  • waveform conditioning
  • waveform monitoring
  • waveform generation
  • signal processing
  • point-by-point analysis

The Signal Processing VIs contain some digital filter design VIs similar to VIs in the Digital Filter Design Toolkit. For example, the Butterworth Coefficients VI is similar to the DFD Butterworth Design VI and the Parks-McClellan VI is similar to the DFD Remez Design VI. However, the Digital Filter Design VIs provide more capabilities, such as support for arbitrary phase and magnitude specifications and fixed-point filter design.

Although the VIs have similar functionality, the results you get might be different because the design algorithms are different. For information about working with the Signal Processing VIs and the Digital Filter Design VIs refer to the manufacturer's web site at ni.com
