Figure 12.  (a) A prewhitened version of the minimum-phase wavelet shown in Figure 11a and the inverse of this prewhitened version. (b) The autocorrelations of the prewhitened wavelets shown in (a). Note that the prewhitening was done by increasing the zero-lag value of the wavelet autocorrelation shown in Figure 11b to obtain the autocorrelation of this wavelet shown here. (c) The amplitude spectra of the wavelets shown in (a). Note that the amplitude spectrum of the inverse shown here has better characteristics than does its counterpart in Figure 11c.
