Hand coloured albumen print. otheruses2 Carrier A porter , also called a bearer , is a person who shifts objects for others. Historical meaning Human adaptability and flexibility early led to the use of humans for transportation shifting gear. Uneven terrain, such as in mountains, alleyways and markets, and a lack of formed roads, such as in jungle, makes the use of porters economical where one can hire people to shift inexpensively. Porters were used commonly as human Pack animal beasts of burden in the ancient world, when labor was generally cheap, especially in societies that depended on slavery. The ancient Sumer ians, for example, enslaved women to shift wool and flax. The use of bearers for litter vehicle litter s to shift persons of rank or religious idols, especially in formal processions, seems to have extended their practical function into that of ceremonial status symbol in the often conservative protocol of court and cult, a role continued into the 20th century with the papal sedia gestatoria and possibly echoed in the modern funeral pallbearer .

unreferenced date April 2009 NO CARRIER capitalized is a text message transmitted from a modem to its attached device typically a computer , indicating the modem is not or no longer connected to a remote system. NO CARRIER is a response message that is defined in the Hayes command set . Due to the popularity of Hayes modems during the heyday of dial up connectivity, most other modem manufacturers supported the Hayes command set. For this reason, the NO CARRIER message was ubiquitously understood to mean that one was no longer connected to a remote system. Carrier tone Carrier tone redirects to this heading.

In telecommunications , a carrier wave or carrier is a waveform usually sinusoidal that is Modulation modulated modified with an signal electrical engineering input signal for the purpose of conveying information. ref citeweb title Carrier wave with no modulation transports no information. url http www.utexas.edu research cemd nim Agif CarrWave.html publisher University Of Texas accessdate 2008 05 30 ref This carrier wave is usually a much higher frequency than the input signal. The purpose of the carrier is usually either to transmit the information through space as an electromagnetic wave as in radio communication , or to allow several carriers at different frequencies to share a common physical transmission medium by frequency division multiplexing as, for example, a cable television system . Frequency modulation FM and amplitude modulation AM are common modes of modulating the carrier. In the case of single sideband modulation SSB , the carrier is suppressed and in some forms of SSB, eliminated . The carrier must be reintroduced at the receiver by a beat frequency oscillator BFO .

In analogue TV technology, residual carrier is the ratio of carrier level which is modulated by the maximum video signal to the unmodulated carrier level. Video signal Main Video signal Video signal VF or more formally composite video signal CVS is the signal which carries the video information as well as some auxiliary signals for synchronizing. In all systems 0 300 mV level is reserved for auxiliary signals and 300 1000 mV is reserved for video information. In monochrome TV, 300 mV or sometimes 350 mV corresponds to black and 1000 mV corresponds to white. In color TV depending on the system used, superimposed color subcarrier may have slightly higher values.

Unreferenced date March 2008 A definition in semiconductor physics , carrier lifetime is defined as the average time it takes for a minority carrier to Carrier generation and recombination recombine . The process through which this is done is typically known as minority carrier recombination . The energy released due to Carrier generation and recombination recombination can be either thermal, thereby heating up the semiconductor thermal recombination or non radiative recombination , one of the sources of waste heat in semiconductor s , or released as photon s optical recombination , used in light emitting diode LEDs and semiconductor laser s . Carrier lifetime plays an important role in Bipolar junction transistor bipolar transistors and solar cells . Carrier lifetime in semiconductor lasers In semiconductor lasers, the carrier lifetime is the time it takes an electron before recombining via non radiative processes in the laser cavity. In the frame of Laser diode rate equations rate equations model , carrier lifetime is used in the charge conservation equation as the time constant of the exponential decay of carriers. The dependence of carrier lifetime on the carrier density is expressed as ref L.A. Coldren and S.W. Corzine, Diode Lasers and Photonic Integrated Circuits , Wiley Interscience, 1995 ref math frac 1 tau n N A BN CN 2 math where A, B and C are the non radiative, radiative and Auger recombination coefficients and math tau n N math is the carrier lifetime.
