Definitions for "Spectrum"
The several colored and other rays of which light is composed, separated by the refraction of a prism or other means, and observed or studied either as spread out on a screen, by direct vision, by photography, or otherwise. See Illust. of Light, and Spectroscope.
A luminous appearance, or an image seen after the eye has been exposed to an intense light or a strongly illuminated object. When the object is colored, the image appears of the complementary color, as a green image seen after viewing a red wafer lying on white paper. Called also ocular spectrum.
A wavelength or frequency band of electromagnetic radiation that contains information about the radiating source of energy. Optical astronomers rely on the spectrum of light from red to blue (visible spectrum) for detailed information carried by absorption or emission lines, color appearance and brightness. An optical instrument called a spectrograph refracts the light into a spectrum of color with a grating or prism.

A spectrum (plural: spectra) is a condition or value that is not limited to a specific set of values but can vary infinitely within a continuum.
In functional analysis, the concept of the spectrum of an operator is a generalisation of the concept of eigenvalues for matrices. Operators on infinite-dimensional spaces may have no eigenvalues.
Spectrum is the debut album of fusion drummer, Billy Cobham. Released in 1973, Spectrum is regarded as one of the most important and essential albums within the fields of drummers and the jazz fusion genre, despite its common critical vituperation. The album contains much influence of the music of Miles Davis and Mahavishnu Orchestra, with whom Cobham had previously collaborated extensively.

Keywords:  airwaves, infancy, fcc, hdtv, viewers
The airwaves, licensed to broadcasters by the federal government and administered by the FCC, over which broadcasters transmit their signal to television sets and other devices. Since broadcasting's infancy, TV stations have used analog spectrum. In recent years, TV broadcasters have invested in new equipment allowing them to transmit over digital spectrum, which allows them to provide HDTV programming to viewers. Analog spectrum is expected to be returned eventually to the government for auction to wireless telecommunications providers and other potential users of the spectrum.
