| Abstract: | The basic principle of measuring weak signal with extremely unstable chaotic system is proposed. A simple chaotic circuit is designed. According to the sensitivity of a chaotic system on its initial condition, this measuring system can reach an unexpected high precision and be used to measure very weak signals. We give the necessary conditions of a chaotic measuring system and discuss some relative theoretical and technical matters. |
