Electronics Workbench a circuit simulator

Electronics Workbench
Electronics Workbench is the best circuit simulator and testing tool available.

Designing and testing an electronic circuit is a tedious job. Testing is the area where a computer program can be of help; then you will not need to worry that anything will burn up if things go wrong somewhere. Also, the advantage of using ideal components is provided.

Electronics Workbench includes all the tools needed to inspect any electronic or electrical circuit. The circuits can be simulated using ideal components as well as regular ones. It includes a library with a huge list of analog and digital components. If the component you are looking for is not available, you may create it and save it on the user section of the library. It can be done either by editing a component or creating a new one. You will find the chip makers very useful.

Version 5 is a very old one. The component library is somewhat small but it is quite enough for a beginner. The 74xx digital ICs and the general analog ICs, like 741, and also the 555 timer, DAC, ADC, etc., are available. All we need to do is set up the circuit by dragging the components including the measurement devices, function generator, etc., and click on the start button.

Analysis with graphs is available too. It is very useful in constructing bode plots, etc. The program comes with a lot of circuit examples so that you can easily study them. The Circuit Design Community on the Internet is the best source for Electronics WorkBench example files and projects.

The newer versions, like the latest one 10.1, include a lot more components and tools.Download Here

Electronics Engineer

Executive Summary By Jonathan E Richards

 The job of an electronics engineer is to research, design and test electrical components in order that electricity is effectively and efficiently utilised in equipment. o Altering the design of products in order to make them work more efficiently

Electrical engineers have access to a large number of employers from the government (defence and MOD departments), to telecommunications companies, research establishments, electronic equipment manufacturers, digital technology and automotive sector, utility companies, hospitals and educational organisations.



Salaries vary according to the sector worked in. Most electrical engineers work in areas where there is a lot of manufacturing and work for small to medium sized firms. If working in Europe, engineers can apply for status as a European engineer (Eur Ing) which provides professional recognition abroad and increased employability.



How To Market To Electronics Engineering Industry

Executive Summary By Alexander Gordon

Electronics industry is a very huge industry, and engineers, who are very hard to be convinced, take most of the purchasing decisions. Therefore, if you are planning to market your products to electronics industry, you have to be more cautious in your marketing efforts.



Engineers are interested in quality and attributes of the product. How Can You Market Products to Engineers?



A recent survey says engineers have two types of information needs:



Heads - Down Information: This kind of information provides guidelines to the engineers for fixing work related problems. It also includes information about features of products. For such information, engineers prefer using web sites.



Keeping theses differences in mind, you can plan and implement your message and media strategies. Online marketing helps you provide detailed information to the clientele, whenever the demand for it. Engineers spend most of their time in researching and fir this, they use the World Wide Web.

Digital Electronic Scales

Executive Summary By Nicole Roberts

Accuracy : Perhaps the greatest benefit that digital electronic scales have over analog scales is their increased accuracy. This makes digital electronic scales the scales of choice in laboratories and other places where even the most minute particle can make a difference. Of course, accuracy just isn't limited to weighing those "specks", digital scales also are more accurate at showing overall weight.

Less Human Error : Digital scales also make for less human error when reading the scales. While analog lines use lines to mark off increments of weights, digital scales always show digits. Digital electronic scales also have the benefit of being able to distribute the information of the scale to various people and locations faster than analog scales.



How to Choose a Digital Signature Solution

Executive Summary By Olga Pulisman

There are 6 simple points to consider when choosing a Digital Signature Solution (standard electronic signature) for your organization. To ensure a low Total Cost of Ownership (TCO) and a speedy Return on Investment (ROI) from your Digital Signature solution, read on.



1. Seals Documents - This is the basic building block of a true digital signature solution. Tip: Only digital signatures based on Public Key Infrastructure (PKI) technology can truly seal a document.

2. Multiple Application Support - Many digital signature solutions support only PDF and Word applications, which may be sufficient support for some. Tip: Make sure the applications you intend to sign in your organization are supported by the solution you choose.



3. Graphical Signatures - Of the standard applications that have digital signature capacity, almost all lack graphical signature support. Graphical signatures ensure the signature is visually noticeable, and have a psychological impact: the signer is reassured they have signed the document and that it is legally compliant.



Tip: Occasionally, different graphical signatures are required (e.g., initials, full signature).

4. Multiple Signatures - Many digital signature solutions do not allow altering the document once a signature is applied.

Tip: If your company requires several people to digitally sign a document, ensure that your solution offers this feature.



IT staff can find themselves spending weeks every year managing the selected digital signature solution. Costs can skyrocket.



5. Seamless User Registration - Implementing your digital signature solution must be as simple as possible. Tip: It should take a single click to ensure your document is sealed and legally compliant.



6. Total Cost of Ownership - Not everyone considers TCO when purchasing a digital signature solution.

Learning to Design an Electronic Circuit Properly

Executive Summary By Frederic C Padilla

Usually, circuit is made with some basic parts such as capacitors and resistors. Those basic parts are then built into some several combination that structure building blocks for other circuits.



Some people who have enough experiences might not find any difficulty in designing electronic circuit. First, you need to know well about the characteristics and behavior of either intermediate or advanced components of electronic circuit. Sometimes, you can find sample circuits that will help you get more information in using the parts. Some parts that usually contain this information are including semiconductors such as diodes, transistors, as well as op-amps.



Second, you should also learn more about some basic circuits used in many kinds of electronic devices. You will also get this information easily from any basic electronics text. For example, you can have more practices in modifying a Light-Emitting Diode (LED) circuit.



By following those simple steps, you will easily get used to design electronic circuit properly.



Simple Ways To Understand The Filter Capacitors In Electronic Circuits

Executive Summary By Jestine Yong

You could see mica capacitors, ceramic capacitors, tantalum capacitors, aluminum electrolytic capacitors, paper capacitors and etc. Electronic Field - Act as filter to remove ripple in power supplies;



- As inter stage signal coupling capacitors- A capacitor will not pass DC, but an AC signal will go through;



- Tuning resonant circuits, oscillator circuits;



- Decoupling in power supplies and amplifiers;



- As part of timing circuit; and



- As waveshapers and filters



In today's article I'm going to talks about capacitor act as filter to remove ripple from power supplies. Usually, the filter includes one or more capacitors. The capacitors are then placed between the DC line and ground. The value of the capacitors is chosen carefully to give the filter circuit a certain timing constant or TC. This unwanted noise signal can cause problems in electronic circuit. If all capacitors checked okay I would then move on to another circuit. Why not one filter capacitor is enough for each DC line voltage? The answer is that the big filter capacitors (large value) at the secondary side of power supplies is to smooth the DC and remove unwanted lower frequency noise. The small blue capacitor has very high chances to go fully shorted compare to electrolytic capacitor which is very rare.

Using Electronic Devices Makes Your Life Better!

Executive Summary By Justin Ferguson

By using these devices they allow you to do a task faster which gives you the time to do more tasks, so each device actually improves your life and allows you to accomplish more with your day to day activities, which in turn gives you more free time to enjoy electronic devices such as the ones that provide entertainment.



Current estimates on internet access is that approximately 25% of the world's population has access, the number seems low, but for North America alone the access rate is 73%, so through computers and the world wide web, access to knowledge has become very easy. Then there are other spin offs from manufacturing electronic devices like marketing and advertising a lot of which is put on or used in the electronic devices we've already bought, and they tell us how our lives can be even better with newer electronic devices, all these things come from these two urges.



Smart Tips to Take Your Electronic Devices Overseas

Executive Summary By Alexander O Mcgee

As the first step, the voltage of all your devices that you want to take overseas should be checked. If you find that your device says 110v - 220v, it means that the device comes in dual voltage so that you do not have to convert the voltage if you want to carry it with you.



If you find that the device is not dual voltage, the second step that you should do is to buy the small step-down converter or the transformer for helping you converting the voltage. Basically, most devices that you can buy in the USA come with thin, vertical metal prongs, while the standard overseas for the devices is round metal prongs.

Wholesale Electronics

Executive Summary By Aaron Silverman

What are wholesale electronics? Here is a short sketch of what's in wholesale electronics.

Wholesale electronic shops are wholesale distributors, liquidators, and/or exporters of consumer electronic products. Many consumer electronic and computer products are now available wholesale. Wholesale electronics now include communication products, electronic components and production equipment, home appliances, medical devices, IT products, safety or security products, and even fashion electronics.

Wholesaler electronics shops buy large quantities of products. Some wholesale companies buy directly from manufacturers who produce the appliances, gadgets, and PC accessories. If you are planning on finding some supplies from wholesale electronics, first learn about the reputation of the wholesaler. Find feedback on their products, especially if they offer used or refurbished items.

You will also find Bluetooth watches, car audios, DVD players and recorders, camcorders, cell phones, spy gadgets, and MP3 players of all brands. Wholesale electronics are usually picking up sales at this time. Just as with other wholesale items that can be drop shipped, electronics items can be shipped directly from your company name, but coming from the wholesaler.



A Practical Tip For Wholesale Electronics

Executive Summary By Kato Jasmine

Most of the people have fascinations for brand electronic items. Nowadays, consumers not only crave for branded items but also want to have items of impressive and eye-catching features at minimum costs. The idea of wholesale electronics thus flourished. Wholesale electronics, a widely used term nowadays, are electronic products sold directly to the customers at the retail prices without the involvement of middlemen. A large number of wholesale electronics sites are there to provide products to the customers directly from China.

Wholesale electronics suppliers buy electronic items like consumer electronics, gadgets, security equipment and PC accessories from the local manufacturers and then they sell those to consumers at wholesale price.
