虚实结合的实验方法在“信号与系统”实验中的应用

Application of Virtual and Practical Combining Experimental Method in the ＂Signal and System＂ Experimental Teaching

在信号与系统实验教学过程中，采用硬件实验与Matlab仿真软件实验相结合（即虚实结合）的方法．在软件仿真实验过程中，学生不仅可以随意修改参数，比较实验结果，而且还可自行设计系统进行模拟，加强了学生的综合设计能力；在硬件实验中，学生熟悉了实验仪器和设备，掌握了测量方法，动手能力及分析问题的能力得到了提高．通过这种虚实结合的实验方法，强化了实验结果，收到了很好的效果．

During the ＂Signal and System＂ experimental teaching process, the method of combining hardware experiment with Matlab emulation software experiment is used. In the emulation experiment, the students can not only amend parameter and compare experimental results, but also design system and simulate. By so doing, their comprehensive de.sign ability is strengthened. In the hardware experiment, the students are familiar with instruments and equipment and learn the testing methods, and their practical and analytical abilities are proved. By this combined experimental method, we beef up experimental result, and have good effect.
