- 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
DFT进行频谱分析时的三种现象
- DFT进行频谱分析时的三种现象 1、混叠：对连续信号采样，要求连续信号是带限的，采样频率要足够高。Fs应满足Nyquist采样定理才不产生混叠。 采样前加低通滤波器防混叠 2、频谱泄漏：DFT对时域信号进行了截断（相当于采样信号乘了一个窗函数），时域的乘积相当于频域卷积，改变了原信号频谱。 改用其他窗函数（非矩形）改善泄漏。 3、栅栏现象：DFT 只给出了频谱在采样点上的取值，采样点间的频谱内容丢失。-DFT spectrum analysis of a
