| Digital Signal Processing is too theoretical and involves a great variety offormula operation. Beginners often find it difficult to learn, therefore needexperiments to deepen their grasp and application of knowledge. But the traditionalexperimental methods can not perfectly complement theoretical knowledge, so anexperimental software simulation system needs to be designed. With the help of thissystem, students can improving their understanding and application of knowledge.Besides, it can also help colleges save experimental funds and resources.The method design and experimental platform of the basic theoretical knowledge,which adopts MATLAB as the tools, is carryed out in this paper. Combined with thetoolbox, the method design which is important knowledge for students to be mastered,is implemented intuitively by m program, which enhance students’ learning interest.By the experimental platform which use GUI as the tool, this system meets theplenty of experimental projects which have strong applicability and flexibility becausethe conditions can be reset,and realizes lots of the demonstration and validation. TheComprehensive experimental project of noise filtering which can examine students’comprehensive practical ability of DSP is be designed in this platform,and it is used totest the ability of learn knowledge. To expand students’ knowledge level and cultivatethe interest of signal processing algorithm, the platform finally designs an interfaceof All-phase FIR Filter,and through the actual operation and comparison with thetraditional design method, it can make the students understand the importance ofalgorithm design and enhance their motivation to learn Basic theories.The experimental platform designed in the paper, mostly have been put intoteaching and has achieved good results,and all this shows that the design content hashighly pertinence and applicationl. |
