The discrete wavelet transform decomposes a discrete time signal into an approximation sequence and a detailed sequence at each level of resolution. The approximation at any resolution is the projection of the signal onto the orthogonal space spanned by the translates of an analyzing scaling function. The choice of scaling function can have a large impact on the error in the approximation at a given resolution. A systematic method for generating scaling functions is developed. This method… CONTINUE READING
