Decompositions of noise-added signals. For comparison, in (A), we show a typical signal with noise level 0.5, and in (B) we show the averaged Fourier transforms of all 50 realizations with noise level 0.5. In (C–F), we show the decompositions obtained for the sample signal from: (C) a shallow rolloff Butterworth filter of order 3; (D) a steep rolloff Butterworth filter of order 3; (E) a dyadic filter bank; and (F) empirical EMD.
