Any signal that can be represented as an amplitude that varies with time has a corresponding frequency spectrum. This includes familiar concepts such as [[visible light]] ([[color]]), musical notes, [[radio frequency|radio/TV channels]], and even the regular rotation of the earth. When these physical phenomena are represented in the form of a frequency spectrum, certain physical descriptions of their internal processes become much simpler.  Often, the frequency spectrum clearly shows [[harmonics]], visible as distinct spikes or lines at particular frequencies, that provide insight into the mechanisms that generate the entire signal.
 
==Light==
 
Light from many different sources contains various colors, each with its own brightness or intensity. A rainbow, or [[prism (optics)|prism]], sends these component colors in different directions, making them individually visible at different angles.  A graph of the intensity plotted against the frequency (showing the brightness of each color) is the '''frequency spectrum''' of the light.  When all the visible frequencies are present equally, the perceived color of the light is white, and the spectrum is a flat line. Therefore, flat-line spectrums in general are often referred to as ''white'', whether they represent light or another type of wave phenomenon (sound, for example, or vibration in a structure).
 
==Sound== <!-- "Audio spectrum" redirects here -->
 
Similarly, a source of sound can have many different frequencies mixed. A [[Musical tone|musical tone's]] [[timbre]] is characterized by its [[harmonic spectrum]].  Sound in our environment that we refer to as ''noise'' includes many different frequencies.  When a sound signal contains a mixture of all audible frequencies, distributed equally over the audio spectrum, it is called [[white noise]].<ref>

Sound spectrum is one of the determinants of the [[timbre]] or quality of a [[sound]] or [[note]]. It is the relative strength of pitches called [[harmonic]]s and [[partial]]s (collectively [[overtone]]s) at various frequencies usually above the fundamental frequency, which is the actual note named (e.g. an A).
 
[[image:sonagraphe.jpg|thumb|center|Spectrum analyzer or Sonagraph]]
 
The [[spectrum analyzer]] is an instrument which can be used to convert the [[sound|sound wave]] of the musical note into a visual display of the constituent frequencies.  This visual display is referred to as an acoustic [[spectrogram]]. Software based audio spectrum analyzers are available at low cost, providing easy access not only to industry professionals, but also to academics, students and the [[hobbyist]]. The acoustic spectrogram generated by the spectrum analyzer provides an [[acoustic signature]] of the musical note.  In addition to revealing the fundamental frequency and its overtones, the spectrogram is also useful for analysis of the temporal [[ADSR envelope|attack]], [[ADSR envelope|decay]], [[ADSR envelope|sustain]], and [[ADSR envelope|release]] of the musical note.
 
==Radio==
 
In radio and telecommunications, the frequency spectrum can be shared among many different broadcasters.  Each broadcast radio and TV station transmits a wave on an assigned frequency range, called a ''channel''.  When many broadcasters are present, the radio spectrum consists of the sum of all the individual channels, each carrying separate information, spread across a wide frequency spectrum. Any particular radio receiver will detect a single function of amplitude (voltage) vs. time.  The radio then uses a [[tuned circuit]] or tuner to select a single channel or frequency band and [[modulation|demodulate]] or decode the information from that broadcaster.  If we made a graph of the strength of each channel vs. the frequency of the tuner, it would be the '''frequency spectrum''' of the antenna signal.

[[Image:triangle-td and fd.png|thumb|A [[triangle wave]] pictured in the time domain (top) and frequency domain (bottom). The fundamental frequency component is at 220 Hz (A2).]]
 
'''Spectrum analysis''', also referred to as [[frequency domain|frequency domain analysis]] or [[spectral density estimation]], is the technical process of decomposing a complex signal into simpler parts. As described above, many physical processes are best described as a sum of many individual frequency components. Any process that quantifies the various amounts (e.g. amplitudes, powers, intensities, or phases), versus frequency can be called '''spectrum analysis'''.
 
Spectrum analysis can be performed on the entire signal. Alternatively, a signal can be broken into short segments (sometimes called ''frames''), and spectrum analysis may be applied to these individual segments. [[Periodic function]]s (such as <math>sin (t)</math>) are particularly well-suited for this sub-division. General mathematical techniques for analyzing non-periodic functions fall into the category of [[Fourier analysis]]. 
 
The [[Fourier transform]] of a function produces a frequency spectrum which contains all of the information about the original signal, but in a different form.  This means that the original function can be completely reconstructed (''synthesized'') by an [[inverse Fourier transform]].  For perfect reconstruction, the spectrum analyzer must preserve both the [[amplitude]] and [[Phase (waves)|phase]] of each frequency component. These two pieces of information can be represented as a 2-dimensional vector, as a complex number, or as magnitude (amplitude) and phase in [[polar coordinates]]. A common technique in signal processing is to consider the squared amplitude, or [[power (physics)|power]]; in this case the resulting plot is referred to as a [[power spectrum]].
 
In practice, nearly all software and electronic devices that generate frequency spectra apply a [[fast Fourier transform]] (FFT), which is a specific mathematical approximation to the full integral solution. Formally stated, the FFT is a method for computing the [[discrete Fourier transform]] of a [[Sampling (signal processing)|sampled signal]].
 
Because of reversibility, the Fourier transform is called a ''representation'' of the function, in terms of frequency instead of time; thus, it is a [[frequency domain]] representation. Linear operations that could be performed in the time domain have counterparts that can often be performed more easily in the frequency domain.  Frequency analysis also simplifies the understanding and interpretation of the effects of various time-domain operations, both linear and non-linear. For instance, only [[nonlinearity|non-linear]] or [[Time-variant system|time-variant]] operations can create new frequencies in the frequency spectrum.
 
The Fourier transform of a ''[[stochastic]]'' (random) waveform ([[noise]]) is also random.  Some kind of averaging is required in order to create a clear picture of the underlying frequency content ([[frequency distribution]]). Typically, the data is divided into time-segments of a chosen duration, and transforms are performed on each one.  Then the magnitude or (usually) squared-magnitude components of the transforms are summed into an average transform.  This is a very common operation performed on [[sampling (signal processing)|digitally sampled]] time-domain data, using the [[discrete Fourier transform]].  This type of processing is called [[Welch's method]].  When the result is flat, it is commonly referred to as [[white noise]].  However, such processing techniques often reveal spectral content even among data which appears noisy in the time domain.
