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.

All these studies are based on considering transmitter as a large circular loop and receiver either at the center of the loop and/or coincident with the loop, over the simple layer/homogenous earth models, and majority of them are based on the computation of TEM responses from their frequency responses only for the central and/or coincident loop configurations, because of the computational intricacies associated with the frequency domain response computation of large loop TEM source for arbitrary receiver positions (except for central and coincident loop configurations) over the layer earth models which involve product of two Basel functions that make the integral unstable and nonconvergent.

According to the different ways to suppress the interference, these suppression methods can fall into three categories: elimination [14,15], time\frequency domain filtering [16,17], and frequency domain preprocessing [18,19,20].
