摘要
In this paper,the relationship between the time window and frequency window of the Gabor transform is discussed and its physical meaning is interpreted; then the relationship between the time window and frequency window of wavelet analysis is compared to the result of Gabor.Based on the above-mentioned result,we explain how the Gabor transform is developed in Wavelet analysis and what the advantage is of wavelet analysis compared with the Gabor transform.
