fourier analysis in English
His theorem, now called the Riesz - Fischer theorem, which he proved in 1907, is fundamental in the Fourier analysis of Hilbert space.
Use "fourier analysis" in a sentence
1. With Abelian it is possible to sample, periodize and perform Fourier analysis on elementary LCAs using homomorphisms between groups.
2. A Fourier analysis shows a semidiurnal component with an amplitude of 1 /2 of that of the diurnal component, phase shifted by 180°.
3. Amplitude reproducibility was somewhat higher under steady-state as compared to transient stimulation; we attribute this to the high noise rejection of the Fourier analysis.
4. The process of Blurring or smearing an image, and its inverse (sharpening or unsmearing) is best understood in terms of spatial frequencies. While an exact description requires the use of Fourier analysis, some idea of what's involved can be conveyed through pictures
