(a) Phase shift of wavelet components of the first difference of h(t) relative to h(t), in blue, and phase shift of wavelet components of the cumulative sum of h(t) relative to h(t), in red. Black lines are at π/2 and −π/2. (b) The driver, h(t), is white noise, with a power spectrum shown in green (the area under the curve represents the wavelet power in a spectral interval), while the power spectrum of the first difference of h(t) is shown in blue and that of the cumulative sum is in red.
