摘要
由于数字滤波器在信号处理过程中应用广泛,所以研究滤波器的设计具有重要的实际意义。文章利用Lab Windows/CVI软件设计了滤波处理界面,该界面包括信号的产生、噪声的叠加和滤波器处理;该界面可以选择多种原始信号与噪声信号,并且可以快速、便捷地修改滤波器的参数。经过实验验证,利用Lab Windows/CVI软件设计数字滤波器,操作简单、功能强大,可以用于实际。
Because of the wide application of digital filter in signal processing, it is of great practical significance to study the design of the filter. With Lab Windows/CVI software, a filter processing interface is designed in this paper, which includes signal generation, noise superposition and filter processing; the interface can choose a variety of the original signal and noise signal, and can quickly and conveniently modify the filter parameters. After experimental verification, designing digital filter with Lab Windows/CVI software is simple and powerful, and can be widely used in practice.
