,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

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
