【摘要】 频率特性仅仅依靠理论分析显得十分抽象,学生不易掌握,而频率特性的实验在实验室开展又比较困难。该文以RC低通滤波器为例,介绍了应用Proteus和Matlab两种仿真软件实现滤波器的频率特性的方法,操作简单,效果直观、形象。更多还原

【Abstract】 Frequency characteristics of filter are the most important.The result of filter processing on the different frequency signal is different.The only theoretical analysis of frequency characteristics is Abstract very much,so students study it difficultly.But experimental research of frequency characteristics is more difficult.Taking RC low-pass filter as an example,simulation experiments on frequency characteristics based on Proteus and MATLAB are introduced.The methods are simple,and the simulating effects are vivid.更多还原
