Spectrum Analysis

Spectral analysis or Spectrum analysis may refer to:

  • Spectroscopy in chemistry and physics, a method of analyzing the properties of matter from their electromagnetic interactions
  • Spectral density 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 for achieving this
  • 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

Famous quotes containing the word analysis:

    “The spider-mind acquires a faculty of memory, and, with it, a singular skill of analysis and synthesis, taking apart and putting together in different relations the meshes of its trap. Man had in the beginning no power of analysis or synthesis approaching that of the spider, or even of the honey-bee; but he had acute sensibility to the higher forces.”
    —Henry Brooks Adams (1838–1918)
