IIR
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.)

通过建立运动模糊数学模型, 进行了消除运动模糊的仿真实验, 维纳滤波恢复运动模糊图像效果较
好。在图像恢复技术中, 点扩展函数( PSF) 是影响图像恢复结果的关键因素, 所以常常利用先验知识和后验判
断方法估计PSF函数来恢复图像。实验表明在实际恢复过程中如果运动模糊图像混入了噪声, 必须考虑到信噪
比、噪声的自相关函数和原始图像的自相关函数对恢复后图像的影响。(Through the establishment of mathematical model of motion blur was conducted simulation experiments to eliminate motion blur, Wiener filter to restore motion-blurred image effect is good. In the image restoration technology, the point spread function (PSF) that affect the results of image restoration a key factor, so often used to determine a priori knowledge and a posteriori estimation PSF function to restore the image. Experimental results show that the actual recovery process if the motion-blurred images mixed with the noise, we must take into account the signal to noise ratio, the noise autocorrelation function and the autocorrelation function of the original image of the restored image effects.)
