The Middletown Norwalk M N TransmissionLine is a 69 mile 112 km , 345 kilovolt AC transmissionline between Middletown, Connecticut Middletown and Norwalk, Connecticut Norwalk in the U.S. state of Connecticut . Construction began in 2006 with the ground breaking at the Beseck Switching Station and was energized in December 2009. Route The M N TransmissionLine begins in Middletown begins at the Scovill Rock Substation in Middletown, and proceeds west to the Beseck Switching Station in Wallingford. From Beseck the transmissionline continues southwest to the East Devon Substation by overhead wires supported by 105 foot 35 m Electricity pylon pylons . At East Devon, the line will connect to the nearby Devon Power Station owned by NRG Energy and the Milford Power Company power plant before going underground. The line will continue underground to the Singer Substation in Bridgeport, where it will connect to the Bridgeport Harbor Generating Station owned by Public Service Electric and Gas Company PSE&G , the Bridgeport Energy Plant owned by Duke Energy , and the Bridgeport waste to energy plant operated by the Connecticut Resource Recovery Agency. From Bridgeport, the line will continue southwest, closely following U.S. Route 1 US 1 , passing Ash Creek to its terminus at the Norwalk Substation. To ease environmental and community concerns, portions of the line are being placed underground, while the overhead portions of the line will traverse mainly rural areas. Northeast Utilities and United Illuminating are constructing the line at a cost of 1.3 billion. As part of the project, UI and NU will reconstruct the existing 115 kilovolt transmission lines located on segments of the M N line s path.

Unreferenced stub auto yes date December 2009 Transmissionline measurement or Transfer Length Measurement is a technique used in semiconductor physics and engineering to determine the ohmic contact contact resistance between a metal and a semiconductor. The technique involves making a series of metal semiconductor contacts separated by various distances. Probes are applied to pairs of contacts, and the resistance between them is measured by applying a voltage across the contacts and measuring the resulting Current electricity current . The current flows from the first probe, into the metal contact, across the metal semiconductor junction , through the sheet of semiconductor, across the metal semiconductor junction again except this time in the other direction , into the second contact, and from there into the second probe and into the external circuit to be measured by an ammeter . The resistance measured is a linear combination sum of the contact resistance of the first contact, the contact resistance of the second contact, and the sheet resistance of the semiconductor in between the contacts. If several such measurements are made between pairs of contacts that are separated by different distances, a Graph of a function plot of electrical resistance resistance versus contact separation can be obtained. If the contact separation is expressed in terms of the ratio L W where L and W are the length and width of the area between the contacts such a plot should be linear , with the slope of the line mathematics line being the sheet resistance . The y intercept intercept of the line with the y axis , is two times the contact resistance. Thus the sheet resistance as well as the contact resistance can be determined from this technique.

Analog or analogue transmission is a Transmission telecommunications transmission method of conveying voice , data, image, signal or video information using a continuous signal which varies in amplitude , phase, or some other property in proportion to that of a variable. It could be the transfer of an analog source signal electronics signal , using an analog modulation method such as Frequency modulation FM or Amplitude modulation AM , or no modulation at all. Some textbooks also consider passband data transmission using a digital modulation method s such as ASK, PSK and QAM, i.e. a sinewave modulated by a digital bit stream, as analog transmission and as an analog signal . Others define that as digital transmission and as a digital signal .
