31LORAN — (LOng Range Aid to Navigation) is a terrestrial radio navigation system using low frequency radio transmitters that uses multiple transmitters (multilateration) to determine location and/or speed of the receiver. The current version of LORAN in… …
32Microwave burn — This article is about injury from direct microwave exposure. For other microwave oven related injuries, see Hazard section of Microwave oven. Microwave burns are burn injuries caused by thermal effects of microwave radiation absorbed in a living… …
33Control of the National Grid (UK) — The National Grid (UK) is the high voltage electric power transmission network in Great Britain, connecting power stations and major substations to ensure that electricity generated anywhere in Great Britain can be used to satisfy demand… …
34Laser beam profiler — A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers ultraviolet, visible, infrared, continuous… …
35Numerically controlled oscillator — A numerically controlled oscillator (NCO) is a digital signal generator which creates a synchronous (i.e. clocked), discrete time, discrete valued representation of a waveform, usually sinusoidal.[1] NCOs are often used in conjunction with a… …
36Quantum well — A quantum well is a potential well with only discrete energy values. One technology to create quantization is to confine particles, which were originally free to move in three dimensions, to two dimensions, forcing them to occupy a planar region …

38DVB-RCT — (Digital Video Broadcasting Return Channel Terrestrial), provides a method by which the DVB T platform can become a bi directional, asymmetric, broadband and wireless path between broadcasters and customers. DVB T when completed with DVB RCT can… …
39Radar signal characteristics — A Radar System uses a Radio Frequency electromagnetic signal reflected from a target to determine information about that target. In any radar system, the signal transmitted and received will exhibit many of the characteristics described below.The …
40Analog television — Analog (or analogue) television encodes television picture and sound information and transmits it as an analog signal: one in which the message conveyed by the broadcast signal is a function of deliberate variations in the amplitude and/or… …
