摘要
在科学技术高速发展的今天,信号处理的重要性愈加突显,研究分析信号特征有着十分重要的意义。文章在MATLAB编程技术和GUI界面设计的基础上,根据FFT变换、离散小波变换、自相关、互相关原理,设计了一个分析信号时域与频域特征的信号处理平台。
With the rapid development of science and technology,the importance of signal processing is becoming more and more prominent.It is of great significance to study and analyze signal characteristics.By using MATLAB programming technology and GUI interface design,a signal processing platform for analyzing the characteristics of signal in time domain and frequency domain is designed according to the principles of FFT transform,discrete wavelet transform,autocorrelation and cross-correlation.
