crosstalk

[′krȯs‚tȯk]
(communications)
The sound heard in a receiver along with a desired program because of cross modulation or other undesired coupling to another communication channel; it is also observed between adjacent pairs in a telephone cable.
Interaction of audio and video signals in a television system, causing video modulation of the audio carrier or audio modulation of the video signal at some point.
Interaction of the chrominance and luminance signals in a color television receiver.
(engineering acoustics)

crosstalk

Undesired signals in one electrical circuit as a result of electrical coupling with another circuit.

crosstalk

(electronics)
Interference caused by two signals becoming partially superimposed on each other due to electromagnetic (inductive) or electrostatic (capacitive) coupling between the conductors carrying the signals. A common example of crosstalk is where the magnetic field from changing current flow in one wire induces current in another wire running parallel to the other, as in a transformer. Crosstalk can be reduced by using shielded cables and increasing the distance between conductors.

crosstalk

(1) Electromagnetic interference that comes from an adjacent wire. "Alien" crosstalk is interference that comes from a wire in an adjacent cable, for example, when two or more twisted wire pair cables are bundled together.

(2) (Crosstalk) An earlier family of communications programs for DOS and Windows from Attachmate Corporation, Seattle, WA (www.attachmate.com). Crosstalk products were originally developed by Microstuf, Inc., later merged with DCA and then Attachmate. It was one of the first personal computer communications programs, originating in the CP/M days. Crosstalk used the Crosstalk Application Script Language (CASL).
