Abstract

In existing textbooks of digital signal processing, there are some deficiencies when narrating the process from FT to DFT, which affects the readers’ understanding and mastering this process to a certain degree. According to the author’s knowledge, this paper introduces the calculation process from FT to DFT through a DFT calculation example and analyzes the contingent aliasing effect, truncation effect, and picket fence effect. It has been proved in practice that narrating the process from FT to DFT through this example can deepen students’ understanding about the origin of DFT concept effectively.
