WebJul 22, 2013 · Discrete Wavelet Transform in MATLAB Ask Question Asked 9 years, 8 months ago Modified 9 years, 8 months ago Viewed 2k times 0 I am working with audio signal processing and need to perform a 3-Band DWT. I am trying to use the dwt function in MATLAB to do this. 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). Examples[edit]
