Case Design and Simulation Experiment for “System Response” in “Signal and System”

The course of “Signal and System” is important with wide coverage, theory and application. The calculation of system response is the main line through the time domain and transformation domain of signal and system. Due to the difficulties in course study, some students' understanding is not deep and comprehensive. Combining with system model, convolution operation, system function, block diagram modeling, Z transform, and program design, “system response” was used for classical difference problems by comprehensive design and simulation experiments. Matlab will be used to simulate the experiment and realize graphic visualization. In addition, the beauty of mathematics, the relevance, applicability and innovation of knowledge were integrated into the ideological and political education of the curriculum. From the feedback result, case design and simulation experiments can integrate theory with practice, restore the problem essence, stimulate students' study interest, and improve comprehensive innovation ability for students' employment.
