From Signal and System to Digital Signal Processing,sampling theorem is an important content of teaching.However,in engineering applications,a large amount of data will cause the waste of storage space.Compressed sensing breaks through the limitations of Nyquist sampling theorem and can achieve sampling at a lower sampling frequency.In order to adapt to the teaching reform under the background of new engineering andprovide an access to the cutting-edge achievements to students,compressed sensing is introduced as a supplement and expansion of traditional teaching for the Nyquist sampling theorem,and good teaching effect is achieved.
