The Haar Wavelet Filter Bank

In this Haar Wavelet worksheet, students solve and complete 4 different problems related to the Haar Wavelet filter bank. First, they define the properties of Haar basis. Then, students compute the matrices for the first, second and third stages of a filter bank on the low-pass output. They also verify that the pure wave forms is defined by rows that are orthogonal and draw a bar graph that represents the pure wave forms.
