| Abstract: | In this paper,it describes the similarities and differences between short-time Fourier transform and the analytic wavelet transform by contrasting their algorithms.Using a built-in analytical signal MishMash of Matlab as an import ,and the results which simulated with the two algorithms on the Matlab will show that analytical wavelet transform has a better time-frequency localized in the use of extracting the frequency of the signal characteristics. |
