• Undesired capacitive, inductive, or conductive coupling from one circuit, part of a circuit, or channel, to another.
• Any phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel.
• In a recording setting, the term "crosstalk" can refer to the leakage (or "bleeding") of sound from one instrument into a microphone placed in front of another musical instrument or singer. A common example is the leakage of the high-pitched, heavily-amplified sound of the lead guitar into the microphones for other instruments.

In telecommunication or telephony, crosstalk is often distinguishable as pieces of speech or signaling tones leaking from other people's connections. If the connection is analog, twisted pair cabling can often be used to reduce the effects of crosstalk. Alternatively, the signals can be converted to digital form, which is much less susceptible to crosstalk. In electronics, capacitive coupling is the transfer of energy from one circuit to another by means of the mutual capacitance between the circuits. ... In electronics, inductive coupling refers to the transfer of energy from one circuit component to another through a shared magnetic field. ... Conductive coupling: Energy transfer achieved by means of physical contact, coupling other than inductive or capacitive coupling. ... This article does not cite any references or sources. ... Channel, in communications (sometimes called communications channel), refers to the medium used to convey information from a sender (or transmitter) to a receiver. ... In telecommunication, signalling (or signaling) has the following meanings: The use of signals for controlling communications. ... In telecommunications a transmission system is a system that transmits a signal from one place to another. ...

In wireless communication, crosstalk is often denoted co-channel interference, and is related to adjacent-channel interference. It has been suggested that this article or section be merged with Wireless. ... Co-channel interference is interference from 2 different radio stations on the same frequency. ... Adjacent-channel interference is interference caused by extraneous power from a signal in an adjacent channel. ...

In integrated circuit design, crosstalk normally refers to a signal affecting another nearby signal. Usually the coupling is capacitive, and to the nearest neighbor, but other forms of coupling and effects on signal further away are sometimes important, especially in analog designs. See signal integrity for tools used to measure and prevent this problem, and substrate coupling for a discussion of crosstalk conveyed through the integrated circuit substrate. There are a wide variety of possible fixes, with increased spacing, wire re-ordering, and shielding being the most common. A simple CMOS Operational Amplifier Integrated circuit design, or IC design, is a subset of electrical engineering, encompassing the particular logic and circuit design techniques required to design integrated circuits, or ICs. ... Assuring signal integrity (SI) is done by electronic circuit tools and techniques that ensure electrical signals are of sufficient quality for proper operation. ... In an integrated circuit, a signal can couple from one node to another via the substrate. ...

With the Hammond organ, an electromechanical organ invented in 1935, "crosstalk" or "leakage" occurs when the instrument's magnetic pickups receive the signal from rotating metal tonewheels other than those selected by the organist. In the 1930s and 1940s, crosstalk was originally considered a defect that needed to be corrected. However, in the 1990s and 2000s, Hammond enthusiasts have come to prize the sound of tonewheel crosstalk as a "vintage" or "authentic" aspect of the Hammond's sound.
