"The authors present a short textbook about the fundamentals of Fourier analysis (such as Fourier series, Fourier transform, and windowed Fourier transform) and wavelet theory (such as continuous/discrete wavelet transforms, multiresolution analysis, decomposition/reconstruction algorithms, and construction of orthogonal/biorthogonal wavelets) with emphasis on the underlying ideas. ... This textbook is mainly written for students in computer science, physics, and engineering." (Manfred Tasche, zbMATH, Vol. 1325.42001, 2016)
