信号谱的测量与分析是无线电技术中的一个基本内容,也是物理学、信息处理及很多工程技术领域的一个基本内容.这就要求人们对无线电信号或其它物理量转换成的电信号作谱分析.1965年Cooley-Tukey提出快速傅里叶变换(以下简称FFT)之后,随着计算技术的高速发展和微处理机的大量使用,适应各种需要的FFT谱分析电子仪器和数字分析系统大量涌现,促使谱分析技术不断发展.近年来谱分析中出现了一
Measurement and analysis of signal spectrum is an essential part of radio technology and an essential element in the field of physics, information processing and many engineering techniques, which requires people to make spectrum analysis of electrical signals converted from radio signals or other physical quantities. In 1965 Cooley-Tukey proposed fast Fourier transform (hereinafter referred to as FFT), with the rapid development of computing technology and the extensive use of microprocessors to adapt to various needs of the FFT spectral analysis of electronic instruments and digital analysis system has emerged, Prompted the continuous development of spectral analysis technology.In recent years, spectral analysis appeared one
