N2 - Window functions are widely used in communication, image, voice, sonar and other information processing. At the same time, the design of window function is closely related to the design of digital filter in the course of digital signal processing, so this content is particularly important in teaching. In order to make students familiar with the design and application of window function, this paper introduces the characteristics and application of window function in detail, and through three experiments, including the effect of whole-cycle sampling on spectral leakage, the effect of different window functions on spectral leakage, and the effect of different window functions on spectral resolution, enables students to better grasp the principle of window function and devote themselves to solving practical problems.
