,The Wigner–Ville Distribution and Time–Frequency Signal Analysis,pproach in the last two decades. The basic idea of the method is to develop a joint function of time and frequency, known as a time–frequency distribution, that can describe the energy density of a signal simultaneously in both time and frequency. In principle,?the time–frequency distributions chara

The Wavelet Transforms and Their Basic Properties,ain difficulties of the Gabor wavelets in the sense that the Gabor analyzing function ..(τ)?=?.(τ ? .)?.. oscillates more rapidly as the frequency ω tends to infinity. This leads to significant numerical instability in the computation of the coefficients 〈.,?..〉.

Multiresolution Analysis and Construction of Wavelets,esolution of a signal is a qualitative description associated with its frequency content. For a low-pass signal, the lower its frequency content (the narrower the bandwidth), the coarser is its resolution. In signal processing, a low-pass and subsampled version of a signal is usually a good coarse a
