We study the asymptotic form as p r ϱ of the Daubechies orthogonal minimum phase filter h p [n], scaling function f p (t), and wavelet w p (t). Kateb and Lemarie ´calculated the leading term in the phase of the frequency response leads us to a problem in stationary phase, for an oscillatory integra
