【Abstract】 In order to change the training method in the training of new engineering talents, combined with engineering practice, this paper designs upsampling/downsampling and filtering experiments of digital signal processing signal course. It uses MATLAB software to realize the functions of signal upsampling, downsampling, filtering, fast Fourier transform and so on. This experiment not only enables students to master the basic knowledge of digital signal processing, but also understand the application of digital signal processing in engineering. It can also stimulate students’ ability to innovate and combine theory with practice, which can effectively improve classroom results.更多还原
