    A transform used to decompose a signal into its frequency components, similar to the Fourier transform. But the time-frequency resolution of the wavelet transform can be adjusted since basis functions with compact support are used, in contrast to the Fourier transform, where sine and cosines are used as basis functions.

Continuous Wavelet Transform - Circuit design

    http://opencircuitdesign.com/~tim/thesis/chapter2.pdf
    the Discrete Wavelet Transform specification, all DWT filter s have compact support. The fact that the DWT can be confined absolutely in time and frequency is pro of that it cannot be implemented by physical filters in a continuous time domain. By being phys ically realizable, the CWT cannot achieve perfect compact support.

    https://ieeexplore.ieee.org/abstract/document/157290/
    It is observed that these algorithms are both special cases of a single filter bank structure, the discrete wavelet transform, the behavior of which is governed by the choice of filters. In fact, the a trous algorithm is more properly viewed as a nonorthonormal multiresolution algorithm for which the discrete wavelet transform is exact.

    So fourier transform of windowed function will never have local support even thought spectrum's fluctuations might be infinitly small. Wavelets, on the other side, are functions which originally do have a local support. So fourier transform of the wavelet will also have local support since no windowing is …

Daubechies wavelet - Wikipedia

    https://en.wikipedia.org/wiki/Daubechies_wavelet
    The Daubechies wavelets, based on the work of Ingrid Daubechies, are a family of orthogonal wavelets defining a discrete wavelet transform and characterized by a maximal number of vanishing moments for some given support.With each wavelet type of this class, there is a scaling function (called the father wavelet) which generates an orthogonal multiresolution analysis
