Crosstalk in Transmissions (http://actelis.com/technology-2)
Before 1881, the quality of
telephone decrease when telephone lines were run close to electrical lines. The
problem generally called as “crosstalk.” As defined by Rouse (2005) that
Crosstalk is “a disturbance caused by the electric or magnetic fields of one
telecommunication signal affecting a signal in an adjacent circuit.”
This electromagnetic interference
could cause microcircuits malfunctions in a such we could hearing a
conversation from another telephone. How to minimize crosstalk or
electro-magnetic interference? The easy answer is by application of a twisted-pair
wires.
Two separate enclosed cables are
intertwined to make a twisted pair, look like a simple method. The shielded one
(with surrounded meshes of fine wires) is to protect transmission, while other,
the unshielded one is not for protection in transmissions through cables. The technology was invented by Alexander
Graham Bell in 1881 to solve the crosstalk problem, is simply by keeping the
pairs twisted right up to the connection, so the circuit to be balancing.
In addition, as suggested by
EETimes (2018) that crosstalk can be rejected by combining a twisted-pair wire
and lowpass filters. The low pass filter is technique to active component of
direct current by blocking main line signals to enter direct current from
transmission, and to allow the maximizing of inductances.
The twisted cables together with lowpass
filters could improve quality of telephone signals and made the cable lines
could be run longer without worry of dropping signal quality. Luckily, this old
invention is useful until recently such as to solve computer slowdown, using in
IT cables and much more.
