| Abstract: | In view of the digital signal processing's problems in learning and teaching,a set of virtual demonstration experiment system for digital signal processing teaching is designed based on LabVIEW programming environment,and two virtual demonstration experiments which are Nyquist sampling theorem and the relation between circular convolution and linear convolution are introduced.Teachers could dynamically demonstrate that the variable signal parameters have an effect on experiment phenomenon in these teaching ... |
