Appeal No. 1998-0512
Application No. 08/477,238
through a solid dielectric substrate. Claim 22 is
illustrative of the claimed invention, and it reads as
follows:
22. An apparatus for reducing crosstalk in a connector
circuit for communications systems, comprising:
means for applying first and second pairs of
substantially equal and opposite electrical signals to an
electrical connector having first, second, third and fourth
primary terminals arranged in a first ordered array with the
second and third primary terminals being between the first and
fourth primary terminals, having first, second, third and
fourth secondary terminals arranged in a second ordered array,
and having circuit means for electrically coupling the first,
second, third and fourth primary terminals to the first,
second, third and fourth secondary terminals, respectively, by
first, second, third and fourth conductive paths on a solid
dielectric substrate connecting and connected to the first,
second, third and fourth terminals, respectively;
means for applying the first pair of substantially equal
and opposite electrical signals to the first and fourth
primary terminals;
means for applying the second pair of substantially equal
and opposite electrical signals to the second and third
primary terminals;
means for reactively coupling sections of the first and
third paths through solid dielectric substrate to cancel
crosstalk induced in the connector circuit; and
means for reactively coupling sections of the second and
fourth paths through the solid dielectric substrate to cancel
crosstalk induced in the connector circuit.
