"Spectral analysis or spectrum analysis is analysis in terms of a spectrum of frequencies or related quantities such as energies, eigenvalues, etc."
A method for decomposing a time series into its underlying frequencies.
"Spectroscopy in chemistry and physics is a method of analyzing the properties of matter from their electromagnetic interactions."
"Spectral estimation is an algorithm that estimates the strength of different frequency components (the power spectrum) of a time-domain signal."
"This may also be called frequency domain analysis."
"A spectrum analyzer is a hardware device that measures the magnitude of an input signal versus frequency within the full frequency range of the instrument."
"Spectral theory, in mathematics, is a theory that extends eigenvalues and eigenvectors to linear operators on Hilbert space, and more generally to the elements of a Banach algebra."
"In nuclear and particle physics, gamma spectroscopy, and high-energy astronomy, the analysis of the output of a pulse height analyzer for characteristic features such as spectral line, edges, and various physical processes producing continuum shapes."
