MATLAB中的信号处理Apps简介

本视频重点介绍了如何使用MATLAB® apps进行信号处理,并通过对一个心电信号的预处理和分析演示了相关apps的功能。

首先,介绍了信号处理的相关MATLAB apps,包括Signal Analyzer app, Filter Builder app, Filter Designer app, Wavelet Signal Denoiser app 和Signal Multiresolution Analyzer app

其次,利用Signal Analyzer app对心电信号进行导入、可视化、分析和预处理。预处理包括滤波和去线性化趋势。

其次,利用Signal Multiresolution Analyzer app进行多分辨率分析,去除代表信号趋势的低频成分,重构出无趋势的心电信号。

最后,总结了使用MATLAB apps进行信号处理的好处。
