1. A method for determining near-end cross-talk effects, the method comprising:
inputting a test signal into at least one conductor of a transmission cable;
receiving a raw cross-talk signal from at least another conductor of the transmission cable; and
processing the raw cross-talk signal in the frequency domain to determine a combination of near-end cross-talk components thereof, said combination of components being characteristic of the near-end cross-talk effects,
wherein the test signal has a frequency that is swept, each time by a predefined sweep frequency step, across a predetermined sweep frequency range, and wherein the near end cross-talk components are cross-talk components of the raw cross-talk signal that are non-periodic over the sweep frequency range or periodic having a repetition period of more than a predetermined number of sweep frequency steps.
