上一节介绍了,我们采集的信号,实际上包含了各种各样的子信号,实际情况中,这些字信号非常复杂,我们在时域看不出来都有哪些频率成分,这时候傅里叶变换就排上用场了。 傅里叶变换的提出让人们看问题的角度从时域变成了频域,多了一个维度。

[导读]在信号处理领域,MATLAB的FFT(快速傅里叶变换)是分析频域特性的核心工具。然而,实际应用中常遇到频谱泄漏、栅栏效应等异常现象,导致频谱分析结果失真。本文将从频谱泄漏的成因、栅栏效应的原理出发,结合MATLAB代码实例,系统阐述两种效应的解决 ...
[导读]在生物医学信号处理领域,MATLAB凭借其强大的快速傅里叶变换(FFT)功能,成为分析心电信号(ECG)和脑电信号(EEG)频域特性的核心工具。通过FFT算法,研究者能够将时域信号转换为频域分布,精准识别信号中的关键频率成分,为疾病诊断和生理机制研究提供 ...
