WebThe wavelet for the Haar basis is ψ ( x) = 1[0,1/2) ( x) − 1[1/2,1)] ( x). Because this Haar wavelet ψ is a step function, any partial sum of the series in Eq. (1) is a step function. Unfortunately, approximation of an analog signal by step functions is not consistent with the continuous, piecewise smooth signal model.

"In mathematics, the Haar wavelet is a sequence of rescaled "square-shaped" functions which together form a wavelet family or basis. Wavelet analysis is similar to Fourier analysis in that it allows a target function over an interval to be represented in terms of an orthonormal basis. The Haar sequence is now recognised as the first known wavelet basis and is extensively used as a teac… " - Hama wavelet
