Haar wavelets
Haar functions have been emerged from 1910 when they were
introduced by the Hungarian mathematician Alfred Haar. Haar
wavelets are the simplest wavelets among various types of wavelets.
They are step functions over the real line can take only three
values 0, 1 and 1. The method has been used for being its simpler,
fast and computationally attractive feature. The Haar functions are
the family of switched rectangular waveforms where amplitudes
can differ from one function to another function. Usually the Haar
wavelets are defined for the interval t e [0, 1) but in general case
t 2 ½A; B, we divide the interval [A, B] into m equal subintervals;
each of width Dt = (B A)/m. In this case, the orthogonal set of
Haar functions are defined in the interval [A, B] by (Saha Ray,
