From: An extended Hilbert transform method for reconstructing the phase from an oscillatory signal
Reconstructing the instantaneous phase by the proposed method: a signal with amplitude and phase-modulation. (a) Observed signal x(t) (Eq. 15). (b) Phase-modulation u(t). The dashed line represents the true phase-modulation u(t), and the red and blue line represents its reconstruction by the HT method and the proposed method, respectively. Note that we plotted a part of signal and the start time of the plot is redefined as 0.
