【摘要】 Matlab是一种功能强大的工程计算及数值分析软件。本文以水稻害虫褐飞虱雄虫求偶鸣声信号为例,利用Matlab信号处理工具箱中的函数对该信号进行时频分析,并进一步探讨了小波分析工具箱、高阶谱工具箱以及神经网络工具箱在昆虫声信号研究中应用的可能性。更多还原

【Abstract】 Matlab is a multifunctional software for project computation and data analysis.Some functions in the signal processing toolbox of Matlab can analyze acoustic signals of insects from time -frequency domain,for example,the courtship signal of the male brown planthopper.The possibility of applying the wavelet toolbox,the higher order spectral analysis toolbox and the neural network toolbox in studying on acoustic signals of insects was discussed.更多还原
