The LabVIEW Wavelet Analysis Tools provide a collection of Wavelet Analysis VIs that assist you in processing signals in the LabVIEW environment. You can use the Continuous Wavelet VIs, the Discrete Wavelet VIs, and the Wavelet Packet VIs to perform the continuous wavelet transform, the discrete wavelet transform, the undecimated wavelet transform, the integer wavelet transform, and the wavelet packet decomposition. You can use the Feature Extraction VIs to detrend and denoise a signal. You also can use these VIs to detect the peaks and edges of a signal.

The Wavelet Analysis Tools provide a collection of commonly used continuous wavelets, such as Mexican Hat, Meyer, and Morlet, and a collection of commonly used discrete wavelets, such as the Daubechies, Haar, Coiflet, and biorthogonal wavelets. You also can create a discrete wavelet that best matches the signal you analyze by using the Wavelet Design Express VI.

The Wavelet Analysis Tools contain Express VIs that provide interfaces for signal processing and analysis. These Express VIs enable you to specify parameters and settings for an analysis and see the results immediately. For example, the Wavelet Denoise Express VI graphs both the original and denoised signals. You can see the denoised signal immediately as you select a wavelet, specify a threshold, and set other parameters. The Wavelet Analysis Tools also provide Express VIs for multiresolution analysis, wavelet design, and wavelet packet decomposition.
