摘要
提出了一种利用模数、数模转换器、存储器来构造非线性函数电路,只要改变存储器的内容,可以很容易地实现任意非线性函数。把符号函数、三阶梯波函数、五阶梯波函数关系式写入存储器,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,成功地实现了基于存储器的三阶JERK混沌电路单方向和多方向网格状混沌吸引子相图并给出了硬件实验结果。
A new method of nonlinear function circuit realization based on ADC,memory and DAC was proposed.By the method any nonlinear function can be easily realized by change contents in memory.Sign function,three-ladder wave function and five-ladder wave function formulae were read in memory and embedded into nonlinear circuits consisting of operational amplifiers,capacitors and adjustable resistors,by which phase diagram of one-way and multi-direction grid-like chaotic attractors of three order JERK chaotic circuit was successfully realized.The results of hardware experiment were given.
