Description: 基于matlab的信号时频分析仿真
MATLAB 软件在多个研究领域都有着广泛的应用。其中,它的频谱分析和滤波器的分析设计功能很强,从而使数字信号处理变得十分简单、直观。本文介绍了时频分析基础理论及一些应用,运用MATLAB 语言实现了旨在构造一种时间和频率的密度函数,以揭示信号中所包含的频率分量及其演化特性的wigner-ville 分布。-Matlab-based time-frequency signal analysis and simulation software MATLAB in a number of research fields as wide Pan application. 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.
