| Zusammenfassung |
| When used with certain parameter values, the multitaper method of spectral analysis has a relatively poor resolution in the wavenumber domain when compared with global power spectra derived using the wavelet transform. We show this finding from analysis of synthetic fractally-distributed data, and from synthetic data representing the deformation of a plate acted on by flexural and convective processes. We further explore the consequences of such disparity upon estimates of the elastic thickness of the continental lithosphere. |
