| Because the curriculum of Signal Processing has many characteristics, such as various content, abstract concept, complex design and so on. The students frequently feel dull with difficulty understanding and grasping, when study this curriculum. In order to enhance the study interest of students and strengthen the ability of understanding and grasping knowledge, put forward developing an experimental software based on Signal Processing. In the experiment software, each experiment can be completed in experimental interface, so students can understand the design method and the abstract concept in curriculum through the experimental way.Since MATLAB has many advantages, such as write program succinctly and efficiently, compile, link and run with high-speed and so on, therefore the design adopts the design function of the graphic user interface in MATLAB to design each experimental interface.The experimental system can complete the experiments of convolution, Fourier transformation, Z transformation, filter design and so on. The student only need to enter the corresponding experimental parameter, then can obtain the output of corresponding graph and data, which can be easy to be understanded and viewed directly. |
