说明：  科恩著“时_频分析:理论与应用”该书全面系统地阐述了时-频分析的理论与应用。全书共分19章，主要内容有：时间分析、频率分析、尺度分析、时间-带宽关系；瞬时频率；密度和局部量；短-时傅里叶变换；时-频分析；魏格纳分布；时-频表示；计算方法；综合问题；空间/空间-频率表示；时间尺度表示；算子；一般联合表示；随机信号和高阶时-频分布。每一个概念都有举例说明，而且还给出了这些方法如何推广到其它的变量，如尺度等。 西安交通大学出版社
(Cohen book when _-frequency analysis: Theory and Applications The book comprehensively and systematically elaborated on when- frequency analysis of the theory and application. Book is divided into 19 chapters, the main elements are: time analysis, frequency analysis, scale analysis, the time- bandwidth relations instantaneous frequency density and local capacity short- when the Fourier transform time- frequency analysis Wigner distribution time- frequency representation calculation method integrated problem space/space- the frequency of express time scales express operator general joint express random signal and high-order time- frequency distribution. Each have examples of a concept, but also how these methods are given to other variables, such as the scale and so on. Xi an Jiaotong University Press)
