The nonuniform discrete fourier transform and its applications in signal processing /
The discrete Fourier transform (DFT) is a widely used tool in many branches of engineering and science, providing information about the spectral contents of a discrete-time signal at equally-spaced discrete frequency points. A generalization of DFT introduced in The Nonuniform Discrete Fourier Trans...
