Discrete Hartley transform (article)
Discrete Hartley transform is a scholarly work, published in 1983 in ''Journal of the Optical Society of America''. The main subjects of the publication include fractional Fourier transform, Fourier transform, noise reduction, Hartley transform, discrete Fourier transform, discrete-time Fourier transform, convolution, inverse, convolution theorem, computer science, Multiplication, mathematics, cyclotomic fast Fourier transform, Discrete sine transform, algorithm, fast Fourier transform, arithmetic, digital signal processing, floating point, Non-uniform discrete Fourier transform, and Discrete Hartley transform. The discrete Hartley transform (DHT) resembles the discrete Fourier transform (DFT) but is free from two characteristics of the DFT that are sometimes computationally undesirable.
