Hungry? Tired? Sick? A new AI tool has been created by scientists to help parents and doctors differentiate between babies& 39; cries.June 06, 2019As most parents already know, differentiating between a baby& 39;s cries for food, tiredness, wetness or if it simply needs some care and attention, can be a real guessing game.
Professor Sir John Ambrose Fleming is one of the great men of radio and electronics.Fleming& 39;s invention of the thermionic valve or vacuum tube could be said to be the beginning of modern electronics. It enabled wireless and later electronics technology to move forward, enabling the first wireless sets with a reasonable performance to be manufactured.
Digital Audio Broadcasting, DAB Tutorial Includes:DAB basicsDAB frequenciesDAB Digital Radio, which is also known as digital audio broadcasting, is an entirely new system for broadcasting and receiving radio stations. As the name indicates signals are broadcast in a digital format to enable CD quality to be achieved.
Burst noise or popcorn noise is a little known form of noise these days. It appears as of sudden step transitions between different level which can manifest itself as a transient at the output of the electronic equipment.This form of noise may not affect some circuits much, but others it can provide some particular problems and issues.
Ham Radio History Includes:Ham radio history overviewEarly foundationsFirst radio hamsEarly ham radio equipmentLicenses introducedCallsignsNational societiesFirst World WarTrans-Atlantic contactsThe history of amateur radio has its beginnings in the very foundations of radio or wireless technology itself.
Computer Technology Includes:How a computer worksCPU central processing unitComputer RAMToday we are used to the fact that computers can undertake a huge number of tasks. They use their processing ability to do a host of tasks from calculating numbers through to running programmes that cover everything from office tasks like word processing to accounting and very much more.
Thermal noise is always present in electronic circuits and it is one of the major sources of noise.In RF circuits, it is often a critical parameter, especially for front end receiver circuits where it is key design parameters.Thermal noise basicsThermal noise is referred to using a variety of names. Thermal noise is the most widely used, but it may also be called Johnson-Nyquist noise, Johnson noise, or Nyquist noise.

The table of the chemical and other properties of elements including the chemical symbol is given below.The chart of the chemical properties of the elements also provides details of the atomic number, atomic weight, specific gravity and the like.Some elements are not stable and have a very short half-life.
Power Supply Circuits Primer & Tutorial Includes:Power supply electronics overviewLinear power supplySwitch mode power supplyOver-voltage protectionPSU specsDigital PowerPower management bus: PMbusUninterruptible power supplyVoltage regulators are widely used in electronics power supply circuits.
USB Chargers Includes:Buy best USB chargerBuy best car USB chargerBattery charges for AAA, AA, C & D batteriesBattery chargers for the standard AAA, AA, C & D cells of batteries that are used in a host of electrical and electronic gadgets come in very useful.Although primary or non-rechargeable cells are widely sued, there is a huge need for chargers for the rechargeable cells.
Often, when building electronics projects, little thought is given thought is given to the connecting wire. While it is possible to & 34;get away with& 34; almost anything for many projects, it is sometimes necessary to connect the various electronics components using the right wire. For example it is often useful to use coloured connecting wire to indicate such items as electronics wire used for connecting the supplies, signals, and grounds.
Soldering Tutorial Includes:Soldering basicsManual soldering: how to solderSoldering ironsTools for solderingSolder - what it is and how to use itDe-soldering - the secrets of how to do it properlySolder jointsPCB solder resistSee also:SMT soldering techniques for PCB assemblyAlthough solder is widely used in the electronics industry and for connecting components and securing them in place, it is sometimes useful to ask what is solder to gain an understanding of what it is and how best to use it.
Phase-change random access memory, P-RAM, is a form of non-volatile memory or computer storage that is faster than the much more commonly used Flash memory technology.Phase change memory can be referred to by a number of names including P-RAM or PRAM, PC-RAM, phase change RAM, and possibly more.Phase change memory is based on a technique known as the memresitor that was initially developed by Hewlett Packard.
Battery Technology Includes:Battery technology overviewBattery definitions & termsNiCadNiMHLi-ionLead acidBatteries are becoming more widely used. As the use of portable and mobile equipment increases, so does the use of battery technology.The increasing demands being placed on batteries has meant that the technology has developed considerably in the past few years, and more development can be expected in the future.
Magneto-resistive RAM, Magnetic RAM or just MRAM is a form of non-volatile random access memory technology that uses magnetic charges to store data instead of electric charges.MRAM memory technology also has the advantage that it is a low power technology as it does not require power to maintain the data as in the case of many other memory technologies.
Webcams Includes:How to buy the best webcamThe level of video conferencing and general video chat increased dramatically as a result of the Coronavirus pandemic. As people saw the advantages of home working, and general video chat, the increased levels of video seen ver the pandemic are set to stay.Whilst most laptops will have their own embedded camera, these tend to be relatively low quality, and often not easy to position properly.
The basic LTE, long term evolution cellular services were launched around 2010 with some advance deployments well before this. It was never envisaged that this initial form of LTE would provide the full performance intended. This required some additional elements that were in what was termed LTE Advanced.
Wireless Meter Bus Includes:Wireless M bus basicsThe Wireless Meter Bus is a variant of the M-Bus or Meter-Bus which is a European standard defined under EN 13757.The Wireless Meter Bus or Wireless M-Bus is aimed at remote reading of gas or electricity meters as well as any other types of meters that may need to be read remotely.
Digital technology has made major advances. Whereas once all electronic circuits were based around analogue techniques, nowadays digital approaches tend to dominate. Not only are there digital or logic circuits, but programmable logic in the form of field programmable gate arrays and other forms of logic circuit are also available.
TV Remote Controls Includes:How to buy the best TV remoteTV remotes are a fact of life these days - modern TV systems with the television, recorder, satellite box, sound bar and possibly more can mean that it is difficult to know which one to use.Then there is the problem of these TV remote controls getting lost - with so many around this is hardly surprising.
