The squared magnitude response of a twisted-pair channel can be modeled as |H(f)|² = exp(-a?f), the constant a is defined by where k is a constant depending on wire gauge, l is a reference line length, and Jig the actual length of the twisted pair under study. The squared magnitude response of the coupling responsible for NEXT has the form |H _NEXT?(f)|² =?f^3/2?where ? is a constant that depends on the type of cable used.

Formulate the expression for the information capacity of the NEXT-dominated channel described here.
