Fig. 3. — Order k = 0, 2, 4 power spectrum estimators $\tilde{P f}$ (first two figures) and wavelet invariant estimators $\tilde{P_{S} f}$ (last two figures) for the signal $f_{3} (x) = e^{- 5 x^{2}} \cos (32 x)$ . Figures 3(a) and 3(c) show small dilations and Figs 3(b) and 3(d) show large dilations.
