写在前面:Stein的四本分析教材为:Fourier Analysis; Complex Analysis; Real Analysis; Functional Analysis 我的阅读顺序是 复分析-傅立叶分析导论-实分析-泛函分析(第一、二本的顺序我觉得不重要,这两本都可单独出来看,内容也相对简单一些,比如可以只读一下复分析那本书,和Ahlfors的复分析对比一下还是很不一样的...
前面讨论的Fourier级数都是适用于圆上的函数或(等价地) R 上的周期函数,这一章我们对整个实轴上的非周期函数建立一个相似的理论(通过定义Schwarz Space) 粗略的讲,Fourier变换是Fourier系数的连续性版本: an=∫01f(x)e−2πinxdx 定义Fourier变换为 f^(ξ)=∫−∞∞f(x)e−2πixξdx 又f(x)=∑...

Tagged Fourier analysis DFT mandalas Posted on 2 September 2023 by John Math books often use some illustration from the book contents as cover art. When they do, there’s often some mystery to the cover art, and a sense of accomplishment when you get far enough into the book to understand...
Special analysis and many other applications often require discrete Fourier transforms (DFTs) to be performed on data sequences in real time and on contiguous sets of input samples. The theory of discrete-time, linear, time invariant systems forms the basis for digital signal processing, and a ...
13 Fourier analysis In Chapter 5 we discussed how functions could be represented as power series using the expansions of Taylor and Maclaurin. Those expansions are valid only within certain … - Selection from Mathematics for Physicists [Book]

前两章讲了Fourier级数的产生与一些基本性质,引入了卷积和good kernels的概念,并且学习了一些特殊的求和。这一章来研究Fourier级数的收敛性。 Fourier级数的收敛性从两个方面来看: 一是“global”(全局) mean…
This small chapter is here to summarize the classical facts of Fourier analysis that will be used in the sequel. We omit the proofs (except for the Poisson summation formula). They can be found in standard textbooks on the subject, for instance in Katznelson (1976), Stein & Weiss (1971)...
