1 设计一个ＦＩＲ数字低通滤波器， 满足一组模拟滤波器的指标参数；分别采用三角窗、hamming窗、blackman窗和kaiser窗进行设计。比较不同窗的设计效果。要求描绘滤波器的脉冲响应、窗函数以及滤波器的幅频和相频响应曲线。 2. 用上述设计滤波器完成几组给定信号的滤波。 3.设计数字高通、带通、带阻滤波器，要求描绘滤波器的脉冲响应以及滤波器的幅频和相频响应曲线。 (1、A design of a FIR digital low-pass filter, analog filters to meet the target of a group of parameters were used triangular window, hamming window, blackman windows and kaiser window design. Window to compare different design effect. Requirements described impulse response filter, window function and the filter amplitude-frequency and phase frequency response curve. 2. Using the above filter was designed to complete several sets of a given signal filtering. 3. Design of digital high-pass, band pass, band-reject filter, the filter impulse response described demand as well as the filter amplitude-frequency and phase frequency response curve.)

该函数给出无限大障板上圆形活塞声源辐射的声场随时间分布状态图，主要包括：声源辐射随传播时间变化的声场二维分布图和随时间变化的动画(This function simply-supported boundary conditions given on circular piston the sound field radiation over time distribution state figure, mainly including: sound radiation to the propagation of 2 d time change acoustic field distribution and change over time the animation )

几种变化检测算法的简单演示，包括比值法，归一化法，相关系数法三种方法(Several simple demonstration of the change detection algorithm, including ratio method, normalization method, three methods of correlation coefficient)

说明：  基于KPCA的对葡萄酒数据的降维处理，将13维数据降维成小于13维的，可选(KPCA-based dimensionality reduction of wine data)

说明：  能够根据已知参数计算同步时钟系统的预期寿命。考虑了多个切换器，考虑了节点损坏后只作为从节点、只作为主节点、总线阻塞等情况。(The expected life of synchronous clock system can be calculated according to the known parameters. Several switchers are considered. The node is only used as slave node, only as master node, and bus is blocked.)

实现多用户MU，通过两次预编码来消除用户间干扰和流间干扰，同时这种处理极大简化了接收机复杂度。(MU-MIMO 。 the first precoding ：ZF-BD the second precoding ：ZF or MMSE)
