The Rolling Stones Disaster At Altamont: Let It Bleed. With four dead and a mess at Altamont, Rolling Stone tries to get to the bottom of what really happened at the. ![]() Crosstalk - Wikipedia. In electronics, crosstalk is 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. Crosstalk is usually caused by undesired capacitive, inductive, or conductive coupling from one circuit, part of a circuit, or channel, to another. ![]() In cabling. Interference between two pairs in a cable is measured at the same end of the cable as the interfering transmitter. Crosstalk is undesirable. Bleed For This CastIn crosstalk, the signals traveling through adjacent pairs of wire in twisted- pair cabling interfere with each other. The pair causing the interference is called the . The NEXT value for a given cable type is generally expressed in decibels per feet or decibels per 1. NEXT value varies with the frequency of transmission. The higher the NEXT value, the greater the cable. Generally specifications for cabling (such as CAT 5) include the minimum NEXT values. The specification was developed to directly address the effect of transmissions on multiple adjacent pairs on the pair being tested and is relevant to all connecting hardware and associated communications cables. Gigabit Ethernet through Cat- 6 uses all four wire pairs simultaneously and bidirectionally. The additional wire pair usage and growing bandwidth increase the need to keep NEXT in check. PSNEXT is a way of measuring NEXT in the ends of cables due to their close proximity. The (cited) SMP white paper states that the testing process for PSNEXT consists of measuring all pair- to- pair crosstalk combinations and then summing all of the values for each pair. Far end crosstalk (FEXT)Interference between two pairs of a cable measured at the other end of the cable with respect to the interfering transmitter. This is an electrical effect and can be quantified with a crosstalk measurement. Interchannel crosstalk applies between the two channels of a stereo system, and is usually not very important on modern systems, though it was hard to keep below the desired figure of - 3. B or so on vinyl recordings and FM radio. Crosstalk between channels in mixing consoles, and between studio feeds is much more of a problem, as these are likely to be carrying very different programmes or material. Crosstalk measurement is made on audio systems to determine the amount of signal leaking across from one channel to another. The IBA drew up a weighting curve for use in crosstalk measurement that gives due emphasis to the subjective audibility of different frequencies, as shown here. This is still in use, despite the demise of the IBA, and in the absence of any international standards is worth adopting.
![]() Alternatively, the signals can be converted to digital form, which is much less susceptible to crosstalk. In wireless communication, crosstalk is often denoted co- channel interference, and is related to adjacent- channel interference. 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. In full- field optical coherence tomography. Dutch Soccer / Football site.
