IMACC results of the synthetic signals with asymmetric oscillation and nonstationary envelope. (A-D) IMFs (black lines) and their instantaneous amplitudes or envelops (red lines), and (E-H) AACC of the same signals used in Fig. 4. (A, E) p2/p1 = 1, (B, F) p2/p1 = 4, (C, G) p2/p1 = 9, and (D, H) sawtooth.
