Wavelet Analysis VIs

June 2008, 371421B-01

Installed With: Advanced Signal Processing Toolkit. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

Use the Wavelet Analysis VIs to perform transforms and inverse transforms between signals and coefficients. You can use these VIs to perform denoising, detrending, probability density function estimation, peak detection, edge detection, and ridge detection on a 1D or 2D signal.

The VIs on this palette can return general LabVIEW error codes or specific wavelet analysis error codes.

SubpaletteDescription
Continuous Wavelet VIsUse the Continuous Wavelet VIs to compute the continuous wavelet transform with real-valued wavelets and the analytic wavelet transform with the complex-valued Morlet wavelet.
Discrete Wavelet VIsUse the Discrete Wavelet VIs to compute the discrete wavelet transform or the inverse discrete wavelet transform, the undecimated wavelet transform or the inverse undecimated wavelet transform, the integer wavelet transform or the inverse integer wavelet transform, and the arbitrary path transform or reconstruction.
Feature Extraction VIsUse the Feature Extraction VIs, based on the multi-resolution wavelet analysis, to perform denoising, detrending, probability density function estimation, peak detection, edge detection, and ridge detection.
Utilities VIsUse the Utilities VIs to read data files, to use demonstration data, and to display the squared magnitude or the phase of the wavelet coefficients of a signal on an intensity graph.
Wavelet Packet VIsUse the Wavelet Packet VIs to compute various wavelet packet analyses, such as wavelet packet decomposition, wavelet packet reconstruction, and various operations on the wavelet packet tree.
