对声音信号进行butter低通滤波,对录入的信号进行傅里叶变换，同时对比滤波前后，声音信号的不同(Butter sound signal low-pass filtering, of the Fourier transform of input signals, while before and after filtering, different sound signal)

I am a third year master major in automation at Shanghai Jiao Tong University, P. R. China. With tremendous interest in Industrial Engineering, I am writing to apply for acceptance into your Ph.D. graduate program.

实现一个函数编写的程序，通过符号计算求出f函数的导数 (Written procedures to implement a function, obtained by symbolic computation function, the derivative of f)

在傅立叶变换光学中夫琅和费衍射场的强度分布就等于屏函数的功率谱。因此我们可以直接将光屏进行傅立叶变换，再处理得到衍射图样。(In the Fourier transform optics, Fraunhofer diffraction field intensity distribution is equivalent to the power spectrum display function. Therefore, we can directly Guangping Fourier transform, and then to handle any diffraction pattern.)
