| Abstract: | Because of the changing of working environment, the parameter of chaotic circuit will be drifted, so that it can not get more precise measurement by the distance of chaotic orbits. An improved method of chaotic measurement to reduce the drift of parameter is presented in the paper. Based on the theory of mirror-image constant current circuit, three identical dynatrons and some of diodes are used to make up of the loops of charge and discharge in nonlinear RC oscillator. The experiment results in this simple circuit show that it can get more precise measurement successfully. |
