71Universal asynchronous receiver/transmitter — A universal asynchronous receiver/transmitter (usually abbreviated UART and pronEng|ˈjuːɑrt) is a type of asynchronous receiver/transmitter , a piece of computer hardware that translates data between parallel and serial forms. UARTs are commonly… …
72Matched filter — In telecommunications, a matched filter (originally known as a North filter[1]) is obtained by correlating a known signal, or template, with an unknown signal to detect the presence of the template in the unknown signal. This is equivalent to… …

74Modified AMI code — Modified AMI codes are Alternate Mark Inversion (AMI) line codes in which bipolar violations may be deliberately inserted to maintain system synchronization. There are several types of modified AMI codes, used in various T carrier and E carrier… …
75Soliton (optics) — In optics, the term soliton is used to refer to any optical field that does not change during propagation because of a delicate balance between nonlinear and linear effects in the medium. There are two main kinds of solitons: spatial solitons:… …
76Distress radiobeacon — PLB redirects here. For other uses, see PLB (disambiguation). Emergency position indicating radio beacons or EPIRBs Distress radio beacons, also known as emergency beacons, ELT or EPIRB, are tracking transmitters which aid in the detection and… …
77sound reception — Introduction response of an organism s aural mechanism, the ear, to a specific form of energy change, or sound waves. Sound waves can be transmitted through gases, liquids, or solids, but the hearing function of each species is particularly …
78Speed of light — The speed of light in the vacuum of free space is an important physical constant usually denoted by the letter c . [NIST and BIPM practice is to use c 0 for the speed of light in vacuum in accord with international standard ISO 31 5. See… …
79Non-return-to-zero — The binary signal is encoded using rectangular pulse amplitude modulation with polar non return to zero code In telecommunication, a non return to zero (NRZ) line code is a binary code in which 1 s are represented by one significant condition… …
80Data transmission — Data transmission, digital transmission, or digital communications is the physical transfer of data (a digital bit stream) over a point to point or point to multipoint communication channel. Examples of such channels are copper wires, optical… …
