Effects of changes in ϵ on the resonant and phase-resonant properties of the linear system (29)–(30) for $\alpha =1$. a Envelope-plane diagrams for $ϵ=0.01$ (left), $ϵ=0.1$ (middle), and $ϵ=1$ (right). b Impedance (Z) profiles. c Phase (ϕ) profiles. The parameter values correspond to the autonomous systems presented in Fig. 4a
