摘要
讨论了Ｇａｂｏｒ变换的时间窗和频率窗的关系以及Ｇａｂｏｒ变换的物理意义，进而讨论了Ｗａｖｅｌｅｔｓ的时间窗和频率窗的关系，从而阐述了如何从Ｇａｂｏｒ变换发展到Ｗａｖｅｌｅｔｓ，及Ｗａｖｅｌｅｔｓ与Ｇａｂｏｒ变换比较所具有的优点。
In this paper, firstly the relationship between time window and frequency window in Gabor transformation is discussed, while its physical meaning is interpreted. Then the relationship between time window and frequency window in Wavelets is compared to result of Gabor. Based on the result mentioned above, we expound how Gabor transformation is developed to Wavelets, and what advantages of Wavelets over Gabor transformation.
