refimprove date February 2008 In telephony , pair gain is a method of transmitting multiple Plain Old Telephone Service POTS signals over the twisted pair s traditionally used for a single traditional subscriber line in telephone systems. Pair gain has the effect of creating additional subscriber lines. This is typically used as an expedient way to solve subscriber line shortage problems by using existing wiring, instead of installing new wires from the central office to the customer premises. The term was invented in the middle 20th century by analogy with earlier use of gain to extend telephone local loop s far from the telephone exchange . A pair gain system consists of concentrator s or multiplexer ... copper cable pair. The signals are then separated into individual subscriber lines at the customer premises. The pair gain unit which performs the multiplexing can be as simple as providing ... connection. A larger analog pair gain system made by Anaconda in the 1960s provided seven lines.

Unreferenced date March 2007 Confusing date March 2007 A split pair is a wiring error where two connections that are supposed to be connected using the two wires of a twisted pair are instead connected using two wires from different pairs. Such wiring negates the benefit of using twisted pair in the first place and is likely to cause errors in high rate data lines and increase Interference communication interference on voice lines, especially on long runs. When using registered jack connections and other connection schemes that use modular connector s it is very easy for the unwary to introduce split pairs. The easiest way to wire such a connector is to put the pairs next to each other but this will not result in correct pairing.

Unreferenced date October 2006 In chemistry , an electron pair consists of two electrons that occupy the same molecular orbital orbital but have opposite spin orbital spin s. Image Covalent&PolarBond.png right thumb 200px MO diagram s depicting covalent left and polar covalent right bonding in a diatomic molecule . In both cases a bond is created by the formation of an electron pair. Because electrons are fermion s, the Pauli exclusion principle forbids these particles from having exactly the same quantum numbers . Therefore the only way to occupy the same orbital, i.e. have the same orbital quantum number s, is to differ in the spin quantum number . This limits the number of electrons in the same orbital to exactly two. The pairing of spins is often energetically favorable and electron pairs therefore play a very large role in chemistry . They can form a chemical bond between two atoms as a lone pair . fill the core electron core levels of an atom. Because the spins are paired, the magnetic moment of the electrons cancels and the contribution of the pair to the magnetic properties will in general be a diamagnetism diamagnetic one . Although a strong tendency to pair off electrons can be observed in chemistry, it is also possible that electrons occur as unpaired electron s. In the case of metallic bonding the magnetic moments also compensate to a large extent, but the bonding is more communal so that individual pairs of electrons cannot be distinguished and it is better to consider the electrons as a collective ocean . A very special case of electron pair formation occurs in superconductivity the formation of Cooper pair s.

Electron s, within an electron shell around an atom , tend to distribute themselves as far apart from each other, within the given shell, as they can due to each one being negatively charged . The mutual repulsion is slightly reduced between two electrons, though, if they have opposite Electron magnetic dipole moment spins . Consequently, as an electron shell starts to become filled up, the electrons become organised in pairs. Covalent bond s form between atoms by sharing electrons in their outermost electron shells, in such a way as to give the effect of filling those incomplete shells. Some of the pairs of electrons in such a shell, therefore, are already part of the original atom, and are referred to as lone pair s. The remainder are shared with the other atom, and constitute the bond itself with that atom these form the shared pair s . ref Coulson, E.H., et al. 1971 . Chemistry students book 1 topics 1 to 12 .

Blumlein Pair is the name for a Stereophonic sound Various methods of stereo recording stereo recording technique invented by Alan Blumlein for the creation of recordings that, upon replaying through headphones or loudspeakers, recreate the spatial characteristics of the recorded signal. The pair consists of an array of two matched microphone s of bi directional figure 8 pickup pattern, positioned 90 from each other. Ideally, the transducers should occupy the same physical space as this is impossible the microphone capsules are placed as close to each other as physically possible, generally with one centered directly above the other. The array is oriented so that the line bisecting the angle between the two microphones points towards the sound source to be recorded see diagram . The pickup patterns of the pair, combined with their positioning, delivers a high degree of stereo separation in the source signal as well as the room ambiance. The Blumlein pair produces an exceptionally realistic stereo image, but the quality of recordings is highly dependent on the acoustics of the room and the size of the sound source. Both ribbon and condenser microphones can be used for Blumlein pair recording. A few types of stereo ribbon microphones B & O, Royer, AEA have even been purpose built for just this type of recording. Several types of stereo condenser microphone Neumann, AKG, Schoeps have ... Pair. During the period when Bumlein s patent http worldwide.espacenet.com publicationDetails originalDocument ...
