| Abstract: | As for a number of unknown frequencies of square wave signals existed in the practice,the paper presents the detecting method by using the nonlinear chaotic dynamic system.Duffing equation is transformed,it finds the simulating model to calculate square wave frequency by using directional crossover technique.The technique is feasible through analyzing the calculating results.At the same time,it brings forward the possibility to better detecting the period signal frequency. |
