针对一个混和正弦波信号，设计FIR滤波器，给出了三种设计方法：凯塞窗函数设计带通滤波器法、FDATool设计法实现凯塞窗函数滤波器的低通、带通和高通三种滤波效果以及椭圆低通滤波器的设计法。利用matlab软件实现。(Sine wave for a mixed signal design FIR filter, gives the three design methods: Kaiser window function design band-pass filter method, the FDATool Design Kaiser window function low-pass filter, band-pass and high passthree filter effects, and elliptic low-pass filter design method. Using matlab software.)

一个chirp信号，用来描述连续震动的正弦函数。(A chirp signal, which is used to describe the sine function of continuous vibration.)

说明：  L1svd，一种经典的稀疏信号表示估计doa的方法，包含窄带和宽带，本代码使用的阵列为均匀圆阵。(L1svd, a classical sparse signal representation method for DOA estimation, includes narrowband and wideband. The array used in this code is a uniform circular array.)

边缘是指图像中像素灰度有阶跃变化或屋顶状变化的那些像素的集合。学会并掌握使用matlab进行图像的边缘检测，设计用户界面实现上述功能。 实际问题： 1、采用matlab Guide设计图像界面，可以读入并显示图像，设计实现以下功能的菜单，点击相应的菜单（如radio button）在图像界面上可以显示相应的功能。 2 使用sobel检测算子； 3 使用prewitt检测算子； 4 使用canny检测算子； (Edge is refers to the image pixel has a step change in the collection of those pixels or roof shape change. Learn and master using matlab for image edge detection, design the user interface to realize the function. The real problem: 1, Guide design based on matlab image interface, can be read and displayed image, design and implement the following function menu, click on the corresponding menu (such as a radio button) in the image on the interface can display the corresponding function. 2 use the sobel detection operator 3 use prewitt detection operator 4 use the canny detection operator )

说明：  以直驱永磁风力发电系统为研究对象，提出了一种双变化率步长的最大功率跟踪混合控制策略， 并用MATLAB 进行风力发电系统建模与控制策略的仿真验证。(Taking direct drive permanent magnet wind power generation system as the research object, a hybrid control strategy of maximum power tracking with double rate of change step is proposed, and the modeling and control strategy of wind power generation system are simulated and verified by MATLAB.)

用功率谱的方法求系统频率特性，采用MATLAB仿真，输入信号为Chirp信号和Multitone信号。(Using power spectrum method for frequency characteristics of the system using MATLAB simulation, the input signal for the Chirp signal and Multitone signal.)
