The Wavelet Transform and Its Basic Properties,y at low frequencies. These difficulties led to a problem of finding a suitable reconstruction formula. In order to resolve these difficulties, Morlet first made an attempt to use analytic signals .(.) = .(.) exp{.(.)} and then introduced the wavelet . defined by its Fourier transform

Fourier Transforms and Their Applications,ry differential equations, partial differential equations, and integral equations are discussed. Included are some examples of applications of multiple Fourier transforms to important partial differential equations and Green’s functions.

,Newland’s Harmonic Wavelets,ts Fourier transform .(.) is zero except for an octave band of frequencies. Furthermore, he generalized the concept of the harmonic wavelet to describe a family of mixed wavelets with the simple mathematical structure. It is also shown that this family provides a complete set of orthonormal basis functions for signal analysis.

on, and sampling theory. One of the main reasons for the discovery of wavelets and wavelet transforms is that the Fourier transform analysis does not contain the local information of signals. So the Fourier transform cannot be used for analyzing signals in a joint time and frequency domain. In 1982,
