The core content of digital signal processing, mainly is the signal transmission and processing, identification and so on. When the signal system is a carrier of information, information processing. Therefore, in order to better research signal and system of basic theory and method, help students better understand and master of digital signal processing theory knowledge, in the experimental process by MATLAB, the platform for puteraided design. MATLAB algorithm is used to develop, data visualization, data analysis and numerical calculation of the advanced technology and the interactive language environment. As a powerful scientific puting platforms, it almost to satisfy all puting requirements. As for simulation and program design and visualization of generality demand has increased, emphatically improve the MATLAB graphical user interface, greatly satisfy the needs of the users. GUIDE of matlab is a quick development graphics user interface for a teaching experiment software of digital signal process has been designed and DSP experiments,a new puter aided instruction mode is derived throught this system which bing matlab and active and this interface is friendly and open,this system is beneficial for the students to prehend DSP theory and improves the teaching effect and efficiency. Key words: digital signal process。作為強大的科學(xué)計算平臺，它幾乎滿足所有的計算要求。 設(shè)計的目標(biāo)任務(wù)
