Theory and operational rules for the discrete Hankel transform
Theory and operational rules for the discrete Hankel transform is a scholarly work, published in 2015 in ''Journal of the Optical Society of America''. The main subjects of the publication include fractional Fourier transform, Fourier transform, mathematical analysis, noise reduction, Hankel transform, Spectral density estimation, S transform, Hartley transform, discrete Fourier transform, convolution, orthogonality, inverse, Mellin transform, Circular convolution, convolution theorem, Bessel function, mathematics, discretization, integral transform, Discrete sine transform, digital signal processing, and Discrete Hartley transform. The authors propose and evaluate the theory of a DHT that is shown to arise from a discretization scheme based on the theory of Fourier-Bessel expansions.
