摘　　要：二阶低通电路属于动态电路。由于参数或电路结构的改变其响应也会发生相应的改变。利用MATLAB/GUI(图形用户界面)分析其频率特性能够通过图形用户界面动态演示电路规律,通过观察和比较,学生可以加深对电路规律的理解和掌握。在仿真中,教师可以对电路所涉及的参数直接修改,由计算机实时显示出该电路的响应波形。仿真结果表明,该分析方法占用的内存很小,能够实时分析和演示基本电路规律。The second-order low-pass circuit is a kind of dynamic circuit.After the parameters or the circuit structures have changed,the output response will chang promptly.The frequency characteristics was analysed by using MATLAB/GUI.The Circuit rule can be displayed,thus through observation and comparison,the students can further understand and grasp the circuit law.In simulating process the teacher may change the parameters directly,then the response waveform will be displayed on the computer.The simulation result shows that the analysis only occupied a very small memory block.The basic circuit law can be analyzed and illustrated in real-time.
