This disambiguation page lists articles associated with the same or a similar title.
  • Stub Electromagnetic spectrum: The range of electromagnetic waves covering all frequencies and wavelengths. [e]
  • Stub Spectrum (linear operator): A set of values {λ} characteristic of an operator O mapping a Banach space into itself such that O xλ = λ xλ for some nonzero vectors xλ. [e]
  • Developing Article Political spectrum: A reference line locating political positions in a one-dimensional continuum from left-wing (egalitarian leaning) to right-wing (hierarchy supporting) [e]
  • Developing Article Vibrational spectrum: The set of frequencies exhibited by regular, periodic motions of the parts of a mechanical system relative to one another that persist once excited without requiring an external driving agency. [e]
  • Stub Action spectrum: Scientific terminology for the correlation between specific wavelengths of the light spectrum and corresponding physiological activity. [e]
  • Stub Spectrum bias: Differences between the type of patients in the clinically relevant population and the study population, which leads to an overestimation of the sensitivity and specificity of a test. [e]
  • Developing Article Spread spectrum: A communications technique in which the information to be transmitted travels redundantly over multiple channels (e.g., frequencies, time slots), the number and identity of which may change. It provides greater immunity to noise and electronic attack, makes it harder to intercept, and can increase capacity of a shared medium. [e]
