Butterworth wavelets are introduced and it is shown that they constitute a large class of orthonormal wavelets. Advantages of this approach are the simplicity of the analyzing wavelet design, connections with the digital filter design techniques, FIR and IIR type of implementations and computational savings in the IIR case which gives rise to fast wavelet transform algorithms. A mirror representation and nonorthogonal wavelet expansion are discussed in this context.
