Exempel på hur man kan använda SPECTRAL i en mening

• The proportion reflected is not only determined by properties of the surface itself, but also by the spectral and angular distribution of solar radiation reaching the Earth's surface.
• Atle Selberg (14 June 1917 – 6 August 2007) was a Norwegian mathematician known for his work in analytic number theory and the theory of automorphic forms, and in particular for bringing them into relation with spectral theory.
• Hilbert discovered and developed a broad range of fundamental ideas including invariant theory, the calculus of variations, commutative algebra, algebraic number theory, the foundations of geometry, spectral theory of operators and its application to integral equations, mathematical physics, and the foundations of mathematics (particularly proof theory).
• In graph theory, an expander graph is a sparse graph that has strong connectivity properties, quantified using vertex, edge or spectral expansion.
• In speech science and phonetics, a formant is the broad spectral maximum that results from an acoustic resonance of the human vocal tract.
• The infrared spectral band begins with waves that are just longer than those of red light (the longest waves in the visible spectrum), so IR is invisible to the human eye.
• The term "indigo" can refer to the color of the dye, various colors of fabric dyed with indigo dye, a spectral color, one of the seven colors of the rainbow as described by Newton, or a region on the color wheel, and can include various shades of blue, ultramarine, and green-blue.
• In brief, values of physical observables such as energy and momentum were no longer considered as values of functions on phase space, but as eigenvalues; more precisely as spectral values of linear operators in Hilbert space.
• This is called dispersion and causes prisms and rainbows to divide white light into its constituent spectral colors.
• It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia.
• Sirius is a binary star consisting of a main-sequence star of spectral type A0 or A1, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B.
• Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with spectral lines.
• Both used the newly developed method of flame spectroscopy, in which thallium produces a notable green spectral line.
• Linear predictive coding (LPC) is a method used mostly in audio signal processing and speech processing for representing the spectral envelope of a digital signal of speech in compressed form, using the information of a linear predictive model.
• The benefits of compatible-sideband over conventional AM are increased spectral efficiency due to a reduction in bandwidth of 50% as well as a decrease in wasted power.
• In telecommunications, an equivalent noise resistance is a quantitative representation in resistance units of the spectral density of a noise-voltage generator, given by.
• FWHM is applied to such phenomena as the duration of pulse waveforms and the spectral width of sources used for optical communications and the resolution of spectrometers.
• It is also more accessible than speaking of the noise's power spectral density (in watts per hertz) since it is expressed as an ordinary temperature which can be compared to the noise level of an ideal resistor at room temperature (290 K).
• The dependence of reflectance on the wavelength is called a reflectance spectrum or spectral reflectance curve.
• In fiber-optic communication applications, the usual method of specifying spectral width is the full width at half maximum (FWHM).
