Abstract: Combined the construction of new engineering with the needs of course teaching innovation, a continuous system simulation experiment based on the combination of software and hardware is designed and implemented. The experiment is mainly based on simulation but supplemented by actual measurement verification. Firstly, students are guided to use the basic arithmetic modules composed of operational amplifiers to build an analog system corresponding to the actual system. Then, the Multisim software virtual instrument is adopted to observe the performance of the analog system in the time domain and the frequency domain. Finally, the system performance is tested and verified through the experiment board. The experimental design and teaching guidance have good hierarchy and autonomy, and can stimulate students’ interest in course learning. The experiment has achieved productive applications in the practical teaching of electrotechnics and electronics for undergraduates.
