Abstract: In addition to conducting the traditional RLC series resonant circuit experiment, this paper also designs the indirect measurement experiment of GCL parallel resonant circuit through the principle of equivalent transformation, solving the problem that both the current source excitation and the current testing are difficult to implement. On this basis, the test circuits are built by using the developed experimental kit, and the frequency characteristics of the basic resonant circuits are measured with signal generator and oscilloscope. After that, based on the measurement results, the data analysis and processing are carried out in an orderly manner from different perspectives of student and teacher. Then, with the help of common software, the mathematical calculation and the result display are performed in an efficient and intuitive way. By this means, the error analysis is finally completed under the guide of the teacher. These experimental operation, theoretical analysis, and software training not only deepen the students’ theoretical understanding and improve their practical skills, but also cultivate their engineering literacy from problem discovery to resolution, contributing an important supporting effect in achieving the goals of the experimental teaching.
