| 摘 要： | 研究了三阶JERK混沌电路实现的新方法,提出了利用模数、数模转换器、门电路来构造三阶梯波、五阶梯波等非线性函数,将其嵌入到由运放、电容、精密可调电阻构成的线性系统中去。该数模结合的方法,可提供一种基于混沌信号的伪随机序列,同时也产生连续变化的混沌信号,并给出了该EWB硬件仿真电路单方向和多方向网格状混沌吸引子的相图。

| Abstract: | A new method to realize the 3-order JERK chaos circuit was proposed in this paper. ADC, gates and DAC were used to make the 3-step and 5-1adder wave functions, which were embedded into the linear circuit containing operational amplifiers, capacitors and adjustable resistors. This method can provide a chaotic pseudo-random sequence and a continuous chaotic signal. Besides, the Ewb hardware simulation results of one-way and multi-direction grid-like chaotic attractors were provided. |
