The lifting scheme offers a refined approach to implementing the Discrete Wavelet Transform (DWT) by decomposing traditional convolution-based filtering into a succession of simple, in-place ...

This is a preview. Log in through your library . Abstract The methods of cyclic reduction and Fourier analysis are reviewed together with the FACR algorithm which combines the two methods. It is shown ...

Present order tracking methods for solving noise and vibration problems are reviewed, both FFT and resampling based order tracking methods. The time variant discrete Fourier transform (TVDFT) is ...

An optical discrete time-frequency domain transform technology is proposed for ultra-fast optical waveform measurements. By using the technology, single shot ultrafast optical phenomena in a long time ...
