frequency domain

[′frē·kwən·sē də‚mān]
(communications)
A plane on which signal strength can be represented graphically as a function of frequency, instead of a function of time.
(control systems)
Pertaining to a method of analysis, particularly useful for fixed linear systems in which one does not deal with functions of time explicitly, but with their Laplace or Fourier transforms, which are functions of frequency.
