(color online) Analytically obtained two-parameter bifurcation diagram showing the synchronization dynamics of the variant of MLC circuit in the –f₁ plane with (a) the amplitude of the response system fixed at f₂ = 0.39 and (b) the amplitude of the response system fixed at f₂ = 0.411. The synchronization dynamics is color-coded as follows: red-unsynchronized state (US), green-complete synchronization state (CS), and blue-phase synchronized state (PS).
