Stationary-wave integrated Fourier-transform spectrometry , or standing-wave integrated Fourier-transform spectrometry, is an analytical technique used for measuring the distribution of light across an optical spectrum. SWIFTS technology is based on...
1 Answers 1 viewsIn mathematics, the Fourier transform on finite groups is a generalization of the discrete Fourier transform from cyclic to arbitrary finite groups.
1 Answers 2 viewsIn digital signal processing, the term Discrete Fourier series is any periodic discrete-time signal comprising harmonically-related discrete real sinusoids or discrete complex exponentials, combined by a weighted summation. A specific...
1 Answers 1 viewsIn mathematics, the discrete Fourier transform over a ring generalizes the discrete Fourier transform , of a function whose values are commonly complex numbers, over an arbitrary ring.
1 Answers 1 viewsIn applied mathematics, the nonuniform discrete Fourier transform of a signal is a type of Fourier transform, related to a discrete Fourier transform or discrete-time Fourier transform, but in which...
1 Answers 1 viewsIn Fourier analysis, a multiplier operator is a type of linear operator, or transformation of functions. These operators act on a function by altering its Fourier transform. Specifically they multiply...
1 Answers 1 viewsIn mathematics, the question of whether the Fourier series of a periodic function converges to a given function is researched by a field known as classical harmonic analysis, a branch...
1 Answers 1 viewsIn mathematical analysis, many generalizations of Fourier series have proved to be useful. They are all special cases of decompositions over an orthonormal basis of an inner product space. Here...
