. His name was added to the Distinguished Professor Award Wall in Beardsher Hall. A scholarship fund, the Gordon C. Danielson Fund was established in his name. Danielson collaborated with Cornelius Lanczos to write the paper, ''Some Improvements in Practical Fourier Analysis and their Application to X-ray Scattering from Liquids'' (1942). The Danielson-Lanczos lemma, which appears in this paper, is the basis of the

Cooley–Tukey FFT algorithm The Cooley–Tukey algorithm, named after J. W. Cooley and John Tukey, is the most common fast Fourier transform (FFT) algorithm. It re-expresses the discrete Fourier transform (DFT) of an arbitrary composite size N = N_1N_2 in terms of ''N''1 s ...

discrete Fourier transform In mathematics, the discrete Fourier transform (DFT) converts a finite sequence of equally-spaced samples of a function into a same-length sequence of equally-spaced samples of the discrete-time Fourier transform (DTFT), which is a comple ...
