ConceptHaar wavelet
Haar wavelet
The simplest real-valued wavelet, constructed from step functions. It is computationally efficient but has poor frequency-domain localization, and is often used to demonstrate the basic principles of wavelet transforms.

Real wavelets (such as Haar, Daubechies, Symlet) are computationally efficient, have real coefficients, have low storage and transmission costs, are good at detecting abrupt points and discontinuities in signals, and are widely used in image compression (such as JPEG 2000) and singularity detection.
