Spectral Analysis

A Spectral Analysis is a data analysis that analyzes spectral signatures (such as wavelength signatures).

• Example(s):
  • Spectral Image Analysis.
• See: Spectral Line, Spectrum, Spectroscopy, Spectral Estimation, Frequency Domain, Spectrum Analyzer, Spectral Theory, Banach Algebra.

  • Spectral analysis or Spectrum analysis is analysis in terms of a spectrum of frequencies or related quantities such as energies, eigenvalues, etc. In specific areas it may refer to:
    • Spectroscopy in chemistry and physics, a method of analyzing the properties of matter from their electromagnetic interactions
    • Spectral estimation, in statistics and signal processing, 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
    • Spectrum analyzer, 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, 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
