Investigation of Realization of All-purpose Chaotic Signal Generator

摘要

Chaos is one complex oscillation between periodic oscillation and noise which are generated from the defined system of the realization of nonlinear formula, because chaotic signal is broad-spectrum and hypersensitive in initial value, it attracts wide attention in the fields of the application of secure communication and spread spectrum .Therefore, it is of great importance to investigate and develop new chaotic signal generator to apply the chaotic theory. Based on the results of chaotic theory research, the text illuminates and compares the chaotic signals generated from Chua's circuit and from the Lorenz system based on Labview technology, exploring the methods of generation, the realization of circuit and the problems exist in realization, especially the discretization of continuous system.
