Chaotic method in signal measuring
Huang Wen-gao · Journal of Zhejiang University(Engineering Science) · 2001
The idea of measuring weak signal in unstable chaotic system is described.Fixing initial conditions,chaotic orbits change with parameter of sensor in nonlinear circuit.A distance between two orbits has been defined.By measuring distance of chaotic orbits,very weak signal can be detected because of the sensitive dependence on parameter.The feasibility of this method is verified by computer simulation.
