Ambitus (music)
Ambitus is a Latin term literally meaning enclose, and in Medieval Latin means the "range" of a melodic line, most usually referring to the range of scale degrees attributed to a given mode, particularly in Gregorian chant.
See Spectral band and Ambitus (music)
Astronomy
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos.
See Spectral band and Astronomy
Band emission
Band emission, is the fraction of the total emission from a blackbody that is in a certain wavelength interval or band. Spectral band and band emission are Spectroscopy and Spectroscopy stubs.
See Spectral band and Band emission
Bandwidth (signal processing)
Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies. Spectral band and Bandwidth (signal processing) are spectrum (physical sciences).
See Spectral band and Bandwidth (signal processing)
Colors of noise
In audio engineering, electronics, physics, and many other fields, the color of noise or noise spectrum refers to the power spectrum of a noise signal (a signal produced by a stochastic process).
See Spectral band and Colors of noise
Communication channel
A communication channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel in telecommunications and computer networking.
See Spectral band and Communication channel
Critical band
In audiology and psychoacoustics the concept of critical bands, introduced by Harvey Fletcher in 1933 and refined in 1940, describes the frequency bandwidth of the "auditory filter" created by the cochlea, the sense organ of hearing within the inner ear.
See Spectral band and Critical band
Electromagnetic radiation
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy.
See Spectral band and Electromagnetic radiation
Electromagnetic spectrum
The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. Spectral band and electromagnetic spectrum are spectrum (physical sciences).
See Spectral band and Electromagnetic spectrum
Emission spectrum
The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted due to electrons making a transition from a high energy state to a lower energy state.
See Spectral band and Emission spectrum
Free spectral range
Free spectral range (FSR) is the spacing in optical frequency or wavelength between two successive reflected or transmitted optical intensity maxima or minima of an interferometer or diffractive optical element.
See Spectral band and Free spectral range
Frequency allocation
Frequency allocation (or spectrum allocation) is the part of spectrum management dealing with the designation and regulation of the electromagnetic spectrum into frequency bands, normally done by governments in most countries.
See Spectral band and Frequency allocation
Frequency deviation
Frequency deviation (f_) is used in FM radio to describe the difference between the minimum or maximum extent of a frequency modulated signal, and the nominal center or carrier frequency.
See Spectral band and Frequency deviation
Frequency domain
In mathematics, physics, electronics, control systems engineering, and statistics, the frequency domain refers to the analysis of mathematical functions or signals with respect to frequency (and possibly phase), rather than time, as in time series.
See Spectral band and Frequency domain
Harmonics (electrical power)
In an electric power system, a harmonic of a voltage or current waveform is a sinusoidal wave whose frequency is an integer multiple of the fundamental frequency.
See Spectral band and Harmonics (electrical power)
Hearing range
Hearing range describes the frequency range that can be heard by humans or other animals, though it can also refer to the range of levels.
See Spectral band and Hearing range
Infrared
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. Spectral band and infrared are electromagnetic spectrum.
See Spectral band and Infrared
International Telecommunication Union
The International Telecommunication Union (ITU)French: Union Internationale des Télécommunications is a specialized agency of the United Nations responsible for many matters related to information and communication technologies.
See Spectral band and International Telecommunication Union
Interval (mathematics)
In mathematics, a (real) interval is the set of all real numbers lying between two fixed endpoints with no "gaps".
See Spectral band and Interval (mathematics)
Light
Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. Spectral band and light are electromagnetic spectrum.
Molecular electronic transition
In theoretical chemistry, molecular electronic transitions take place when electrons in a molecule are excited from one energy level to a higher energy level. Spectral band and molecular electronic transition are Spectroscopy.
See Spectral band and Molecular electronic transition
Molecular vibration
A molecular vibration is a periodic motion of the atoms of a molecule relative to each other, such that the center of mass of the molecule remains unchanged. Spectral band and molecular vibration are Spectroscopy.
See Spectral band and Molecular vibration
Passband
A passband is the range of frequencies or wavelengths that can pass through a filter.
See Spectral band and Passband
Radio
Radio is the technology of communicating using radio waves.
Radio spectrum
The radio spectrum is the part of the electromagnetic spectrum with frequencies from 3 Hz to 3,000 GHz (3 THz). Spectral band and radio spectrum are electromagnetic spectrum.

Radio window
The radio window is the region of the radio spectrum that penetrate the Earth's atmosphere. Spectral band and radio window are electromagnetic spectrum.

Range (music)
In music, the range, or chromatic range, of a musical instrument is the distance from the lowest to the highest pitch it can play.
See Spectral band and Range (music)
Spectral line
A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum. Spectral band and spectral line are Spectroscopy and spectrum (physical sciences).
See Spectral band and Spectral line
Spectral width
In telecommunications, spectral width is the width of a spectral band, i.e., the range of wavelengths or frequencies over which the magnitude of all spectral components is significant, i.e., equal to or greater than a specified fraction of the largest magnitude. Spectral band and spectral width are spectrum (physical sciences).

Spectroscopy
Spectroscopy is the field of study that measures and interprets electromagnetic spectra. Spectral band and Spectroscopy are spectrum (physical sciences).

Spectrum (physical sciences)
In the physical sciences, the term spectrum was introduced first into optics by Isaac Newton in the 17th century, referring to the range of colors observed when white light was dispersed through a prism.
See Spectral band and Spectrum (physical sciences)
Transition band
The transition band, also called the skirt, is a range of frequencies that allows a transition between a passband and a stopband of a signal processing filter.
See Spectral band and Transition band
Ultraviolet
