数学实验中用matlab完成的仿真实验，应用matlab的很多仿真功能(Mathematics experiment with matlab simulation experiments completed, many of the matlab simulation function)

频谱分析实践，将信号源发出的信号强度按频率顺序展开，使其成为频率的函数，并考察变化规律，称为频谱分析。研究噪声的频谱是为了深入了解噪声源的特性帮助寻找主要的噪声污染源，为噪声控制提供依据，为噪声控制提供依据。(Spectrum analysis practice, the signal strength of the signal source frequency in order to start by making it a function of frequency, and variation study, known as spectrum analysis. Of the noise spectrum is to understand the characteristics of noise sources to help find the major noise sources, provide the basis for the noise control, provide the basis for the noise control.)
