用双线性变换法设计IIR数字滤波器 滤波就是将外界干扰的不需要的频率滤除掉，一面影响要测试数据的结果。比如如果是心电波的话，如果这是外界有很大的噪声干扰，滤波就是把不必要的信号给抑制掉，以便对心跳的正常测试。通过图比较，滤波后的明显比之前的要平滑，就是滤去干扰噪声的结果。采样间隔对实验有影响，取的过大会导致频率混叠。(Bilinear transformation method using digital filter IIR filter design is to outside interference filter out unwanted frequencies, while the impact to test data results. For example, if it is so heart waves, if this is a great noise outside interference, filtering is unnecessary signal out to the curb in order to test the normal heartbeat. Through chart comparison, after filtering than before to smooth the noise interference is the result of least squares. Sampling interval of the experiment affect take-off frequency of the General Assembly leading to aliasing.)

美国国家航空和宇宙航空局(NASA)研制的跟踪和数据中继卫星系统(TDRSS)的正交信号发生器使用的是阶数为r=11的GOLD序列，序列长为2047，m序列优选对为4445和4005，利用Matlab程序构造出这个序列，并且验证信号的平衡标准，PACF(离散周期自相关函数)和PCCF(离散周期互相关函数)。通过Matlab2009A测试。(NASA developed tracking and data relay satellite system (TDRSS) use of orthogonal signal generator is the order of the GOLD for the r = 11 sequence of length 2047, m sequence pairs for the 4445 and 4005, use of Matlab program to construct the sequence, and verify the balance of the signal standard, PACF and PCCF. Testing by Matlab2009A.)

求峭度，有效值，均方值，还有峰度，是对风力发电机组数据的必要东西(Seeking kurtosis, RMS, mean square value, and kurtosis, the data is necessary for wind turbine things)

利用ICE对图像进行亮度和颜色的调整，可以在图片上对想要进行滤波处理的部分直接进行选择。(Use ICE to adjust the image brightness and color can be in the picture on the part you want to filter processing directly to it.)
