WebIn numerical analysisand functional analysis, a discrete wavelet transform(DWT) is any wavelet transformfor which the waveletsare discretely sampled. As with other wavelet transforms, a key advantage it has over Fourier transformsis temporal resolution: it captures both frequency andlocation information (location in time).
