public class HaarWavelet
extends Wavelet

Haar wavelet. The Haar wavelet is a certain sequence of rescaled "square-shaped" functions which together form a wavelet family or basis. As a special case of the Daubechies wavelet, it is also known as D2. The Haar wavelet is also the simplest possible wavelet. The technical disadvantage of the Haar wavelet is that it is not continuous, and therefore not differentiable. This property can, however, be an advantage for the analysis of signals with sudden transitions, such as monitoring of tool failure in machines.
