Introduction The most commonly used method to circularize the elliptical beam is to use a pair of anamorphic correcting prisms, as shown in Fig.1. The prisms can enlarge or reduce the beam size in one direction while keeping the beam size in ...
TETRA - Terrestrial Trunked Radio for Professional Cellular System TETRA, the European standard for Trunked Radio Systems, is primarily intended for users in the public security sphere, transport, utilities and operators of public Trunked Radio ...
Near Field Communication Interface and Protocol-2 (NFCIP-2) Brief history In 2002, Ecma International formed Task Group 19 of Technical Committee 32 to specify Near Field Communication (NFC) signal interfaces and protocols. The NFC devi ...
Introduction OZ Optics offers a complete line of laser diode to fiber couplers, offering optimum coupling in a small, rugged package. They may be purchased prealigned, ...
Abstract Maritime safety is of paramount concern to the scores of people who make a living from the sea. To ensure their safety and to provide safe navigation for ships, the most popularly used instrument worldwide is the Echo Sounder. The Ec ...
Introduction Most all electronics components generate, store, control or switch electricity in some way. A circuit is made of various components that act together to produce a desired effect. There is a lot to learn about electronics and you ...
Introduction Fiber Optics is the branch of Science (especially - Optical Physics) in which we studied about the Optical Fiber and its Communication i.e. Optical Fiber Communication. Light emitters are a key element in any fiber optics system. ...
Transistors Transistors are semiconductor devices with three leads. For those that don't know "leads" simply refer to the pins or wires coming from a device or component. A very small current or voltage at one lead can control a muc ...
Introduction VHDL is a Hardware Description Language for describing digital system . VHDL a programming language, stands for VHSIC Hardware Description Language. VHSIC is an abbreviation for Very High Speed Integrated Circuit. It can d ...
About The current state of the consumer electronics can be characterized by moving from a single purpose device to a multifunctional device and by moving from isolated devices to a networked device. In this last respect, it is important that p ...
LED stands for Light Emitting Diode. An LED is a semiconductor chip that converts electrical energy into light. The conversion of energy into light happens on the quantum level within the molecular makeup of the semiconductor chip. The process begins w ...
Introduction Power quality has a significant influence on high-technology equipments related to communication, advanced control, automation, precise manufacturing technique and on-line service. For example, voltage sag can have a bad influence ...
Wireless Transmission Wireless technology that is used in small computing devices and mobile communications devices is the same radio technology Guglielmo Marconi used to provide an alternative communication means to the telegraph and the tel ...
Intorduction After being around for 15 years, CAN (Controller Area Network) did not yet reach the peak of its lifetime. The number of CAN nodes sold and installed still rises year by year and currently exceeds the number of 200 million new node ...
The "STA013" and "STA015" integrated circuits by STMicroelectronics are flexible MP3 decoders with good performance. The STA015 is almost fully backwards compatible with the STA013, so this article will focus on the STA013 and mention differences with ...
Since the day Brandon Mayfield, a lawyer from Portland, Oregon, was released from federal custody after a fingerprint had linked him to this year’s Madrid terror bombings, ...
Applications of NFC NFC can be used in a number of ways. Some of the most compelling applications are outlined below. Ticketing and Payment Many major cities around the world use contactless payment systems within the transport in ...
The most fundamental skill needed to assemble any electronic project is that of soldering. It takes some practice to make the perfect joint, but, like riding a bicycle, once learned is never forgotten! The idea is simple: to join electrical parts toget ...
Wireless isn't the black art that many think it is, but it's still a complex process affected by a broad range of variables. Before you select a wireless technology to support a real-time location system (RTLS) in an industrial setting, make sure you k ...
A meter is any device built to accurately detect and display an electrical quantity in a form readable by a human being. Usually this "readable form" is visual: motion of a pointer on a scale, a series of lights arranged to form a "bargraph," or some s ...
Overview of SemiconductorFabrication Technology BasicProcesses: WaferGrowth: Creation of single - crystal substrate material Photolithography: Definition of regions (through a mask) o ...
Whenever electrons flow through a conductor, a magnetic field will develop around that conductor. This effect is called electromagnetism. Magnetic fields effect the alignment of electrons in an atom, and can cause physical force to develop between atom ...
A modern alternative to sending (binary) digital information via electric voltage signals is to use optical (light) signals. Electrical signals from digital circuits (high/low voltages) may be converted into discrete optical signals (light or no light) ...
Today’s wireless networks are characterized by a fixed spectrum assignment policy. However,a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15% to 85% witha ...
Direct Broadcast Satellite (DBS) refers to satellite television (TV) systems in which the subscribers, or end users, receive signals directly from geostationary satellite. Signals are broadcast in digital format at microwave frequencie ...
Inductors do not have a stable "resistance" as conductors do. However, there is a definite mathematical relationship between voltage and current for an inductor, as follows: "Ohms law" for an Inductor v = L ...
Introduction Automation and process engineers increasingly need an understanding of radio basics to properly harness the many wireless automation products now coming on the market. Fortunately, new generations of wireless products are easier to ...
When a new computer modem enters the household, the demands on the home phone line skyrockets. The Internet surfer can use phone time on a par with the most talkative teenager. And the computer modem user c ...
