Measured Signal Based Chaotic Circuits With The Random Number Generator

In order to improve the discrimination ability in weak signal measurement, we proposed a couple-based chaotic circuit approach. Preliminary experiments showed that this method was feasible and effective. In experiments, the resistance coupled circuit and the capacitor coupled circuit were used. Experimental results of the latter was better than that of the former.A chaotic-based random number generator was proposed in the second part of the thesis. Although we had to reduce the influence of noise in the measurement system, we really made use of the noise in the random number generator. As showed in experiments, the binary random numbers built by this generator made good randomicity.
