Abstract: On the basis of demand of the new Electronic Circuit Experiment course and our teaching experience, a new electronic circuit experimental system was developed for basic electronic circuit experiment teaching. Compared with those traditional experimental systems, this system embodies the flexibility of experiments and the self-design processing and exploring investigation are specially emphasized. So it is suitable for designing-based and exploring-based experiments. With this system, the students’ enthusiasm and initiative may be stimulated, and their ability of using integrated knowledge to analyze and solve practical engineering problems, as well as the capacity for independent innovation can be promoted. The system has been applied in the experimental teaching of electronic circuit course for undergraduates in information and electronic engineering department of Zhejiang University. The practice shows good teaching effect has been achieved. Good appraise from the students for this experimental system are also obtained.
