Additional field(s): Computers: Systems, Networks, Engineering (general), IT (Information Technology) | | English term or phrase: crosstalk | Definition from Javvin Technologies, Inc. :
Crosstalk is a type of Interference from an adjacent channel or wire, which is caused by electromagnetic interference, along a circuit or a cable pair. A telecommunication signal disrupts a signal in an adjacent circuit and can cause the signals to become confused and cross over each other.
Example sentence(s): - Crosstalk originating from multiple high-speed data services in the same telephone bundle is a limiting factor for the maximum bit rate, the loop length and the number of data services that a bundle can support. The Pennsylvania State University
- All current crosstalk mitigation techniques require precise knowledge of the crosstalk coupling functions between the twisted pair wires carrying DSL service within a cable binder. Rice Scholarship
- Optical bidirectional transmission systems, such as subscriber systems, where two signals are carried over a single fibre are subject to optical crosstalk. This crosstalk causes an unwanted increase of the bit error rate at the receivers in both channels. Institute of Physics and IOP Publishing

| diafonia | Definition:
Con il termine diafonia (crosstalk) si intende il rumore o interferenza elettromagnetica che si può generare tra due cavi vicini di un circuito o di un apparato elettronico.
La causa è il campo elettromagnetico tempo-variabile che si genera attorno a un cavo in cui passa corrente non costante (segnale). Questo campo magnetico variabile può indurre, in un cavo vicino, una differenza di potenziale e quindi una corrente indotta spuria. In particolare quando si ha un circuito "sorgente" alimentato da una tensione e corrente, esso produce un campo elettromagnetico, in cui è immerso il circuito "ricevitore". Nel secondo circuito si indurrà una corrente (e quindi una tensione).
Si intuisce, anche da questa descrizione semplicistica, che il fenomeno della diafonia appartiene al sistema stesso e quindi non è un problema di emissioni condotte o irradiate. |
