小波变换 Wavelet Transform - WT Wavelet bases, like Fourier bases, reveal the signal regularity through the amplitude of coefficient, and their structure leads to a fast computational algorithm. As opposed to a Fourier base, a wavelet basis defines a sparse representation ofpiecewise regular signals...

Results of the application of wavelet transform for signal processing in white-light interferometry are reported. The mother wavelet frequency is chosen to be the light-source correlogram 1's, and accurate phase measurements are obtained from simple correlation computations. The fringe envelope is also...
Signal processing for Coriolis mass flowmeter based on Hilbert transform In order to process the time-varying output signals of Coriolis mass flowmeter, the method based on Hilbert transform is adopted and investigated. Polyphas... WL Liu,L Zhao,KY Wang,... 被引量: 9发表: 2013年 Phase and...
