摘要
为满足测试测量研究过程中对非平稳信号特征的便捷提取,本文利用时频分析技术并基于LabWindows/CVI设计了时频分析软件系统,整个系统采用模块化的编程思想,用C语言实现STFT算法、Morlet小波算法和Wigner算法,使得软件具有良好的通用性和可扩展性。
In this thesis , the software system of time-frequency based on LabWindows/CVI is used to capture the non -stationary signal characteristics in measurement searching practice .The whole system is implemented by modular programming ideas , and uses C language to implement STFT algorithm , Morlet wavelet algorithm and Wigner algorithm .All of this promotes the versatility and expansibility of system .
