51Spectral asymmetry — In mathematics and physics, the spectral asymmetry is the asymmetry in the distribution of the spectrum of eigenvalues of an operator. In mathematics, the spectral asymmetry arises in the study of elliptic operators on compact manifolds, and is… …
52Spectral concentration problem — The spectral concentration problem in Fourier analysis refers to finding a time sequence whose discrete Fourier transform is maximally localized on a given frequency interval, as measured by the spectral concentration.pectral concentrationThe… …

54Spectral linewidth — The spectral linewidth characterizes the width of a spectral line, such as in the electromagnetic emission spectrum of an atom, or the frequency spectrum of an acoustic or electronic system. For example, the emission of an atom usually has a very …
55Spectral theory of compact operators — In functional analysis, compact operators are linear operators that map bounded sets to precompact ones. Compact operators acting on a Hilbert space H is the closure of finite rank operators in the uniform operator topology. In general, operators …

57Spectral width — In telecommunications, spectral width is the wavelength interval over which the magnitude of all spectral components is equal to or greater than a specified fraction of the magnitude of the component having the maximum value. In optical… …
58Spectral power distribution — In color science, a spectral power distribution describes the power per unit area per unit wavelength of an illumination (radiant exitance), or more generally, the per wavelength contribution to any radiometric quantity (radiant energy, radiant… …
59Spectral mask — In telecommunications, a spectral mask, also known as a channel mask or transmission mask, is a mathematically defined set of lines applied to the levels of radio (or optical) transmissions. The spectral mask is generally intended to reduce… …
60Spectral splatter — In radio electronics or acoustics, spectral splatter (also called switch noise ) refers to spurious emissions that result from an abrupt change in the transmitted signal, usually when transmission is started or stopped.For example, a device… …
