Transient switching behaviors between BMSs and DSs captured by the DFT technique with assistance of the ET-PC. (a) From BMSs to DSs and (b) from DSs to BMSs (intensity in color scale). The transition process includes the degeneration and beating of initial pulses, relaxation oscillation, beating, and regeneration of new pulses.
