Description

technical field [0001] The invention relates to a chaotic circuit, in particular to a chaotic circuit with a constant Lyapunov exponent spectrum. Background technique [0002] In 1963, E.N. Lorenz, the father of chaos, discovered the first chaotic system, which was a simplified model of atmospheric convection and became the starting point and cornerstone of future research on chaos theory. Afterwards, S. Smale proposed 18 famous mathematical problems in the 21st century, and the 14th problem is about the study of the Lorenz system. It can be seen that the scientific significance and research value of the Lorenz system are very important. With the development of chaos theory research, the application of chaos is also expanding rapidly in various fields. At present, the application research of chaos science has developed to how to effectively use chaos, and the application research of chaos in dynamical systems in communication technology and signal processing is more It is i...
