Examples
- To detect transient signals under complex background , a novel method of aliasing - free exponential bilinear time - frequency distribution is presented in this paper , which can avoid the frequency aliasing and information loss existing in the traditional bilinear distributions , reduce the cross - terms effectively and possess high time - frequency resolution
摘要針對復(fù)雜背景條件下瞬時信號的探測，提出一種新的無混疊雙線性時間頻率分布方法，該方法能夠避免常用的雙線性時頻分布中的頻率混疊與信息丟失，有效減小交叉項干擾，而且具有較高的時頻分辨率。 - It mainly includes following aspects : in this paper , firstly implication of wavelet analysis in signal harmonic component extraction is presented in detail , and on this foundation signal given frequency band component extraction method is proposed . then we investigate frequency aliasing phenomenon , reason why frequency aliasing phenomenon is easy happened when wavelet is implied in field of motor fault diagnosis , and frequency bands where frequency aliasing phenomenon is easer happened , and put forward approved morlet wavelet analysis method which can effectively alleviates frequency aliasing phenomenon . third we set up vibration signal detected system , design experiments to obtain three groups of fault signals : eccentricity fault , mixed fault of eccentricity plus mild rub , mixed fault of eccentricity plus moderate rub , and process these data using analysis method proposed in this paper
