Opening Dsp Teaching Experiment Course

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 <>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 <> ,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 .
