Electronics Undesired signals or sounds, as of voices, in a telephone or other communications device as a result of coupling between transmission circuits.2. Ancillary, incidental conversation: crosstalk among members of the panel.crosstalk (ˈkrɒsˌtɔːk) n1. (Telecommunications) unwanted signals in one channel of a communications system as a result of a transfer of energy from one or more other channels2.

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) magnetic printing crosstalkUndesired signals in one electrical circuit as a result of electrical coupling with another circuit.crosstalk (electronics)Interference caused by two signals becomingpartially superimposed on each other due to electromagnetic(inductive) or electrostatic (capacitive) coupling between theconductors carrying the signals. A common example ofcrosstalk is where the magnetic field from changing currentflow in one wire induces current in another wire runningparallel to the other, as in a transformer. Crosstalk can bereduced by using shielded cables and increasing the distancebetween 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).crosstalk
crosstalk [kros´tawk] in cardiology, inappropriate detection of the atrial stimulus by the ventricular sensing mechanism, usually seen with dual chamber pacemakers; it can lead to asystole. Pacemakers are now able to respond to crosstalk with an obligatory ventricular pacing stimulus at a shorter than average A-V interval.crosstalk An artefact in MRI images caused by interference between adjacent slices of a scan, which can be reduced or eliminated by limiting the minimum spacing between slices.crosstalk Related to crosstalk: crosswalkSynonyms for crosstalknoun the presence of an unwanted signal via an accidental couplingSynonymsRelated Words- interference
