Crosstalk

Crosstalk between channels in mixing consoles, and between studio feeds is a much more noticeable problem, as these are likely to be carrying very different programs or material.

Crosstalk measurements are made on audio systems to determine the amount of signal leaking from one channel to another.

The Independent Broadcasting Authority published a weighting curve for use in crosstalk measurement that gives due emphasis to the subjective audibility of different frequencies.

In telecommunication or telephony, crosstalk is often distinguishable as pieces of speech or in-band signaling tones leaking from other people's connections.

There are a wide variety of repair solutions, with increased spacing, wire re-ordering, and shielding being the most common.

In stereoscopic 3D displays, crosstalk refers to the incomplete isolation of the left and right image channels so that one bleeds into the other – like a double exposure, which produces a ghosting effect.
