Abstract

The invention discloses a chaotic circuit for producing multiple butterfly-shaped attractors and an implementation method and relates to a chaotic circuit needed in secret communication. The chaotic circuit is composed of a three-order autonomous circuit (N1), a function sequence generator (N2) composed of symbol functions, a multiplier group (N3) and a phase controller (N4). The chaotic circuit can produce butterfly-shaped chaotic attractors through the multiplier group (N3), and the function sequence generator (N2) composed of the symbol functions can control the chaotic circuit to produce different numbers of butterfly-shaped chaotic attractors. According to the method, by adjusting switch-on and switch-off of a switch k1, a switch k2, a switch k3, a switch k4, a switch k5, a switch k6, a switch k7 and a switch k8, the function sequence generator (N2) composed of the symbol functions is controlled to output different signals, and the chaotic circuit can produce two-wing butterfly-shaped chaotic attractors, four-wing butterfly-shaped chaotic attractors, six-wing butterfly-shaped chaotic attractors, eight-wing butterfly-shaped chaotic attractors and ten-wing butterfly-shaped chaotic attractors. The chaotic circuit can be widely used for secret communication.
