Abstract

The typical means of time-frequency analysis (TFA) and the system the authors have developed recently are introduced in this paper. The TFA system has powerful functions such as short time Fourier transform (STFT), Wigner distribution (WD), wavelet transform (WT) and multi-resolution time-frequency analysis (MRTFA). This paper introduces the theory of main functions and the design of the TFA system. Practical application indicated that MRTFA proposed by the authors is more advantageous in analyzing the signal with small or large scale components than other typical means of TFA.
