自从1965年Cooley和Tucky提出快速付立叶(FFT)算法以后,解决了利用数字计算技术进行付立叶分析所迂到的计算工作量大、计算时间长的老大难问题。接着出现了各种根据FFT算法制造的FFT信号分析仪,为各个科技领域提供了迅速、方便、有效的分析手段。目前,FFT算法和FFT信号分析设备正在不断地渗透到每个涉及付立叶变换的领域。我国从七十年代初期引进、研制,应用FFT算法和设备以来,现在正在逐渐广泛地为各部门、备单位所了介和应用。下面简介FFT分析仪的若干应用。
Since Cooley and Tucky proposed the Fast Fourier Transform (FFT) algorithm in 1965, the crux of computational effort and computational time spent in Fourier analysis using digital computation technology has been solved. Followed by a variety of FFT signal analyzers manufactured according to the FFT algorithm, providing rapid, convenient and effective analysis tools for various fields of science and technology. Currently, FFT algorithms and FFT signal analysis devices are constantly penetrating into every area involving Fourier transforms. Since the introduction, development and application of FFT algorithms and equipment from the early 1970s, our country is gradually and widely used for various departments and units. Here are some applications of the FFT analyzer.
