摘　　要：介绍了基于窗函数的数字滤波器设计方法、基本概念及分类,比较了施加矩形窗和海明窗的带阻滤波器的性能,给出了仿真结果。结果表明:不同的滤波器长度,对于滤波结果是有差别的,在使用中需要按着实际需求作出合理的选择。Introduction was made to the design method of digital filter based on window function, basic concept and category, comparing the performances of band-stop filter with rectangle window and Hamming window, giving out simulation results. The results show that with different filter wave lengths, there are different wave filtering results, and reasonable selection should be made according to actual needs.
