Details
Since the basis functions form an orthonormal set, the approximation of in is , where is determined by the inner product . Students should ask themselves, "What is the interpretation of the projection of into ?" For more information, see Hemut Knaust, "Multi-Resolution Analysis for the Haar Wavelet."
