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:

    “Cubism had been an analysis of the object and an attempt to put it before us in its totality; both as analysis and as synthesis, it was a criticism of appearance. Surrealism transmuted the object, and suddenly a canvas became an apparition: a new figuration, a real transfiguration.”
    —Octavio Paz (b. 1914)
