Figure 2
The observed k-weighted EXAFS spectrum of h-ZnO (Lizandara Pueyo et al., 2010 ) (red) is extrapolated using a pseudo-Voigt function, forward Fourier transformed, weighted by a Kaiser–Bessel window (blue) and then backward Fourier transformed (BFT) to produce an expanded, noise-reduced, spectrum (green dashed). The differences, representing the noise reduced by the Fourier transformation procedure, are shown in yellow using an expanded y scale. |
