Optimization Of Digital Signal Processing Experiment And Design Of Simulation Platform

Digital Signal Processing is too theoretical and involves a great variety of formula operation. Beginners feel it difficult to learn, therefore need experiments to deepen their grasp and application of knowledge. The complexity and ideal of the theory determine that hardware experimental can’t put theory into practice completely. So we need to design a software simulation system as the complement to hardware system. By the help of the system, students can understand the theory of operation related intuitively and accurately, and improve their mastery and application of knowledge. The system with less maintenance expensive is easy to modify and upgrade, and it can realize multidisciplinary sharing. Besides, it can not only to save the experimental funds and resources, but also to make the time and space be effectively extended.The design of the digital signal processing method and experimental platform, which adopts MATLAB as the tools, and somes are simulated and optimized. With the toolbox, and combined with the characteristics of the theory knowledge, the design which is important knowledge for undergraduate students to be mastered, is implemented intuitively by m program. The platform which use GUI as the tool, this system meets the plenty of experimental projects which have strong applicability and flexibility because the conditions can be reset, and realizes lots of the demonstration and validation. In addition to the basic required parts, two projects of the audio noise filtering and All-phase FIR Filter which can examine students’comprehensive practical ability of DSP are designed in this platform, to expand students’knowledge level and comprehensive application ability. Through the actual operation and traditional design optimization, it can make the operators grasp the thought and method of algorithm design and understand the importance of algorithm design, and thereby enhance their motivation to learn Basic theories.The platform have been put intoteaching and has achieved good results, and all this shows that the design content has highly pertinence and application.
