【摘要】 数字信号处理(Digital Signal Processing,简称DSP)是利用计算机或专用处理设备，以数字形式对信号进行采集、变换、滤波、估值、增强、压缩、识别等处理，以得到符合人们需要的信号形式。它已经在通信等领域得到极为广泛的应用。为了推广与普及DSP技术，《数字信号处理》课程已在各大学本科生中开设，目前国内已有部分院校建立了DSP教学实验室，将DSP技术引到实验教学中来，东北师范大学物理系本科电子信息科学与技术专业已经开设《数字信号处理》课程，而DPS实验教学方面仍是一片空白。 针对我系DSP的教学情况，本论文首先论述了开设DSP教学实验课的必要性，接着论述了DSP教学实验系统的选择，并对所选择的台湾掌宇股份有限公司生产的SN-DSP54A型号的数字信号开发实验系统从软件及硬件环境两方面做了简单介绍，然后从DSP的基本理论及我系本科电子信息科学与技术专业学生的具体情况出发，探讨了如何开设DSP教学实验课，并设计出编程练习实验、信号采样实验、数字滤波器实验、快速傅立叶变换(FFT)分析实验等四个DSP实验，以达到如下目的：一推广DSP技术，让学生对DSP技术有更进一步的了解和掌握；二使学生了解到一种新型单片机TMS320C542，与MCS-51及MCS-8098单片机相区别，在了解了这种单片机的独特功能后，激发他们的求知欲；三通过此套DSP系统使学生对复杂可编程逻辑器件(CPLD)有更深入的认识，了解并掌握CPLD的强大功效；四作为《数字信号处理》课程的后续实验课，使学生更深刻体会数字信号处理技术的实现及意义。更多还原

【Abstract】 Digital Signal Processing whose shortened form is DSP processes signal by gathering, transforming, filtering, estimating, enhancing, compressing, discerning signal and so on in digital form ,utilizing computer or special processing facilities ,to gain the needed form of signal .It has been extensively used in many fields such as communication .To popularize DSP technology ,almost every university has offered the course named <<Digital Signal Processing>>to undergraduate student .Presently there are some universities in our country who have established the laboratories for DSP teaching ,so technology on DSP has been applied to experimental teaching .The undergraduate student whose major is electronic information science and technology of physical department in Northeast Normal University has been offered the course of <<Digital Signal Processing>> ,but there is no any course on DSP experimental teaching for him .In the light of such conditions in our department ,this paper discussed the necessity to offer a DSP experimental teaching course first .Then it discussed the selection of DSP experimental teaching system and introduced this selected digital signal development experimental system whose type is SN-DSP54A produced by Zhangyu joint-stock company of Taiwan ,this introduction included its software and hardware circumstances .After that ,this paper discussed how to offer such a course and designed four DSP experiments including writing program exercise , sampling signal , digital filter and fast Fourier transform ,all these based the basic theory of DSP and the concrete circumstances of the major in our department .Designing these four experiments are to attain such main purposes as following rpopularizing the technology of DSP and making the students understand it better ;introducing a new type single chip which is different to MCS-51 and MCS-8098 TMS320C542 to students getting them know its special function and arousing their thirst for knowledge understanding the Complex Programmable Logic Device whose abbreviation is CPLD and its powerful function better ;combiningthe course of {Digital Signal Processing^ to know the realization and meaning of DSP technology better .更多还原
