Next: General formulae Up: No Title Previous: Morlet wavelet and . The modulated waves of section 14 are processed using the Morlet wavelet, and their local norms are shown below. ... The most striking difference with the Mexican-hat transform in section 14 is the shift in emphasis from the individual maxima and minima to the local periodicity. Figure 17: Morlet-wavelet transform of the signal. ... Figure 18: Morlet-wavelet transform of the modulated oscillation. ...
