Generation of Chaotic Beats in a Modified Chua's Circuit Part I: Dynamic Behaviour

This paper and the companion one Cafagna, D. and Grassi, G., Nonlinear Dynamics, this issue] present the new phenomenon of chaotic beats in non-autonomous Chua's circuit, driven by two sinusoidal inputs with slightly different frequencies. In particular, in this paper the behaviour of the proposed circuit is analyzed both in time-domain and state-space, confirming the chaotic nature of the phenomenon and the effectiveness of the design.
