- Digital signal processing is one of the core courses for several engineering specialties, and its theories include five kinds of Fourier transforms, i.e. FT, FS, DTFT, DFS and DFT. The understanding of the inherent relationship between them will directly affect the learning effect as well as the following courses. In this paper, a new way of Fourier transforms teaching is discussed, i.e. based on FT, the influence on the time(frequency) domain signal when sampling it in frequency(time) domain is analysed, and in this way the relationship between the five transforms is discussed. We hope that a better classroom effect will be achieved.
