Sampling and Reconstruction of Wave-Number-Limited Functions in N-Dimensional Euclidean Spaces
The well-known Whittaker-Kotel 'nikov-Shannon sampling theorem for frequency-bandlimited functions of time is extended to functions of multidimensional arguments. It is shown that a function whose spectrum is restricted to a finite region of wave-number space may be reconstructed from its sampIes taken over a periodic lattice having suitably small repetition vectors. The most efficient lattice ...
متن کاملLines in n-Dimensional Euclidean Spaces
In this paper, we define the line of n-dimensional Euclidean space and we introduce basic properties of affine space on this space. Next, we define the inner product of elements of this space. At the end, we introduce orthogonality of lines of this space. provide the terminology and notation for this paper. (4) (a · b) · x = a · (b · x). (6) a · (x 1 + x 2) = a · x 1 + a · x 2. (7) (a + b) · x ...
متن کاملLines on Planes in n-Dimensional Euclidean Spaces
The notation and terminology used here are introduced in the following papers: [1], [5], [12], [4], [9], [14], [13], [8], [15], [6], [2], [3], [7], [11], and [10]. We follow the rules: a, a1, a2, a3, b, b1, b2, b3, r, s, t, u are real numbers, n is a natural number, and x0, x, x1, x2, x3, y0, y, y1, y2, y3 are elements of R . One can prove the following propositions: (1) s t · (u · x) = s·u t ·...
متن کاملFunctions in Sampling Spaces
Sampling theory in spaces other than the space of band-limited functions has recently received considerable attention. This is in part because the band-limitedness assumption is not very realistic in many applications. In addition, band-limited functions have very slow decay which translates in poor reconstruction. In this article we study the sampling problem in general shift invariant spaces....
متن کاملa contrastive study of rhetorical functions of citation in iranian and international elt scopus journals
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
