Carrier Frequency

Carrier frequency is a technical term used to indicate:

  • In telecommunication systems
    • Vaguely speaking, the center frequency or the frequency of a carrier wave (radio wave)
    • The "nominal frequency" or the center frequency of an analog frequency modulation, phase modulation, or double-sideband suppressed-carrier transmission (DSB-SC) (AM-suppressed carrier), radio wave
    • In very technical language: The frequency of the unmodulated electromagnetic wave at the output of a conventional amplitude-modulated (AM-unsupressed carrier), or frequency-modulated (FM), or phase-modulated (PM) radio transmitter
    • In very technical language: The nominal frequency or center frequency of various kinds of radio signals with digital modulation -- provided that the message bit stream is a random uncorrelated sequence of equally probable ones and zeroes ("marks" and "spaces")
  • In molecular biology
    • The rate of occurrence within a living population of a broken chromosome that causes a genetic disorder

Famous quotes containing the words carrier and/or frequency:

    “Because language is the carrier of ideas, it is easy to believe that it should be very little else than such a carrier.”
    —Louise Bogan (1897–1970)

    “One is apt to be discouraged by the frequency with which Mr. Hardy has persuaded himself that a macabre subject is a poem in itself; that, if there be enough of death and the tomb in one’s theme, it needs no translation into art, the bold statement of it being sufficient.”
    —Rebecca West (1892–1983)
