Among them, its spectrum analysis and the analysis of filter design function very strong, so that the digital signal processing is very simple. intuitive. This paper presents a time-frequency analysis of basic theory and some applications, use MATLAB to the structure of a time and frequency density function, to reveal the signal contained in the frequency components and evolution of the air to air-ville distribution.
