Abstract

The invention claims to protect a chaotic circuit and its realization method for generating multi-surrounding coil waves, and relates to a chaotic circuit in secure communication. The chaotic circuit is composed of four parts: fourth-order autonomous circuit N1, adding amplifier N2, piecewise function sequence generator N3 and inverting amplifier N4. The piecewise function sequence generator constructs the piecewise function of the turning point, creates sub-circuits, and controls the number of coils generated by the chaotic circuit in the V2 and V3 directions; by adjusting the Rncc value of the piecewise function sequence generator, the volume of the scroll is adjusted. size. The circuit design method of the present invention is simple, the chaotic signal generation circuit is flexible, and can provide a random number of chaotic signal circuits with continuous coils around the coils. The number of coils around the coils can be controlled by switching the linkage switch, and two coils around the coils, respectively, can be generated. Three-surrounding wire coil wave, etc., and has good performance, and can be widely used in secure communication.
