Examples
- Hungarian - born american physicist . he shared a1963 nobel prize for research on the structure of the atom and its nucleus
维格纳，尤金?保罗生于1902匈牙利裔的美国物理学家。因研究原子及原子核结构而获1963年诺贝尔奖 - It is proved the effect is good . with 3d figure we can know hrv time - frequency distribution and the information of frequency change with time , while this information can not be gotten only in spectrum region
维格纳方法在三维立体图上展示心率变异信号的时频分布时，能揭示出随时间演变频率演变的信息，而这些信息通过单纯的频域分析是不能得到的。 - We found that vlf / lf of hyper thyroibism sickness by using the 2 methods in are high than healthy person . study hrv wd , when using choi - williams window to restrain cross disturb , setting filter parameter a = 0 . 05
本文还对心率变异信号的维格纳分布作了研究，选用choi - williams窗，确定了滤波函数的参数= 0 . 05 ，实际证明抑制交叉项的干扰效果较好。 - The paper discusses mainly the essential theory of time - frequency analysis method and two important tools : wigner - ville distribution , radon - wigner transform that applies to the time - frequency analysis method . and it validates that they can applies to the semic signals processing . the processing result indicates that wigner - ville distribution has well time - frequency collective feature for single component signal , it applies to single component signal processing
处理结果表明，对于单分量信号维格纳-威利分布具有良好的时-频聚集性，因此它对于单分量信号的处理具有很好的效果；而对于多分量信号由于交叉项的存在使得维格纳-威利分布不再很有效，有时甚至会由于交叉项的严重干扰使得信号项变得完全无法分辨。 - Compact in configuration , mightiness in function , convenience in manipulate and high resolution , high efficiency , low cost are all the characteristics of this instrument . in the end , we give a brief introduce about some common analysis methods on oae signal . and lay a emphasis on wavelet and improved wigner - vill used in the analysis of soae and teoae , comparing with the tradition method , these new time - frequent methods have better time - frequent characteristic , are fitter for the oae signals
最后，该文分别对耳声发射信号的常用分析方法进行了介绍，并重点介绍了用小波变换、改进的维格纳分布等方法分别对soae信号、 teoae信号进行分析的情况，与传统的处理方法相比较，时频分析方法由于具有较好的时频分辨率，更适合于耳声发射信号的分析。
