A Look Back at the Time When Analog Stole Digital’s Fame

Analog circuit trainingThe times were 1970s and 1980s when the students thought that mathematics and simple digital logic looked better than the differential functions that used to describe certain analog properties: a time when they probably didn’t have access to the fun of free electronics videos. The twin Ms – monolithic memories and microprocessors took hold of headlines. They were ruling the world and started converting nearly all the academic and commercial electronics into digital paradigm.

This digitization also escorted the increase of digital signal processing. This is the idea that everything must be converted from analog to digital as soon as possible and also must be processed in the digital domain for longer before being converted back to analog to compel a kind of exhibition, and speaker or actuator as well.

Nevertheless, in those days the matter of energy consumption typically was not the first thing people consider about. Nowadays, it is one of the pivotal concerns worldwide. And who can say that it is more acceptable to be extravagant with digital transistor hacks. And this caused a return to using more analog circuit or a move to neuromorphic computing style. Now, with increasing global competition in the context of financial limitations of digital electronics, especially when it is about the consumers, the digital world has become a ground less attractive to play on.

Thus, some companies started drifting towards analog. For them MEMS and sensors were the places to survive. But there was no place to be satisfied. Competition is coming with full vigor as it was in the period of digital province. We are in all probability in a phase of analog supremacy, at the same place where digital was in the 1990s and 2000s.

Fundamental Facts of Digital Electronics:

Digital circuits and systems are considered to be the foundation of electrical engineering. Digital circuits functions using digital and discrete signals. These circuits are usually made combining transistors and logic gates, and at higher levels, with the combination of microcontrollers or other computing chips. Mostly the processor, whether it’s a big processor in your computer or tiny microcontroller, operate in the digital territory.

Analog vs. Digital Circuits:

It is obvious that the way Analog and Digital electronics process a signal is different as the information encoding system is different in them. Here I have included a comparison chart to make easy understanding the apparent disparity between Analog and Digital electronics.

Even a few years ago when computer-aided tools did not become a part of our everyday life, engineering still was not dependant on EDA tools like simulators and logic synthesis. Back then students used to make out their designs as gate-level schematics using pencil and paper. These DIY techniques in a way made them rather good for things like logic minimization, and one of these techniques was Karnaugh maps.

Karnaugh maps vs. the Modern Technology

Nowadays with the emerging availability of computer-aided tools like logic synthesis, Karnaugh maps are perhaps one of the most underused tools in the electronics industry. But whether you need it or not, it is always a suggested to understand basic techniques, because you never know when you will feel the need of something from first principles.

What is a Karnaugh map?

To put in one simple statement, the ‘Karnaugh map’, also known as the ‘K-map’, is a method to simplify Boolean algebra expressions. Its history tells us that it was first originated by Maurice Karnaugh who introduced it in 1953 as a refinement of Edward Veitch’s 1952 Veitch diagram.

Karnaugh maps are predominantly used for their ability to resolve race conditions by adding redundant logic terms that “overlap” adjoining groups. But once again, this sort of thing is handled by logic synthesis these days, but as I told earlier that you never know when you might need to understand this fundamental stuff.

Learn Digital Electronics Tutorials to understand Karnaugh map better

Now, the question arises at first, why we need video tutorials. The technical study of a crucial subject like Digital Electronics requires understanding of its core functioning. To serve this particular purpose, these video tutorials are made. They are the vivid source of useful information on varied topics of Digital Electronics like Karnaugh map.

Video tutorials also allow students to get video tutorials on digital electronics by a monthly subscription at a very affordable price. Video tutorials have now become an important part to students because they add an extra dimension to learning, whether recorded or live, that makes a student’s educational experience more valuable. Transforming a classroom setting to a live scene, these videos add different perspectives and mechanisms that students might not be able to take advantage of in their regular textual learning.

Ok. So, network topology, diagrams, electrical network all are giving you a rough time. You didn’t see it coming when you decided to take up Electronics Science? But it has nothing to do with your understanding of the subject, to be blunt honest. It’s just the tedious pages and dull lectures, very little chance of real-life applications that dry the fun as hay.

AC and DC basic circuit theory connect the entire world. Modern telecommunication largely depends on numbers and networks. Mathematical analysis and quantitative skills are essential parts of learning circuits. All students and aspiring engineers need to have a clear idea on this topic or their learning would be rendered futile in common life applications.

How to Learn AC/DC Circuit Theory Easily

  • The real problem in conventional Tech class is that of instructions. They have a formulated approach to electronics studies. It cannot build a clear, consistent conceptual framework. So you have to emulate models and focus on how to connect ideas. The relationships and distinction between one concept with the other.

    Only math won’t help.  Lay focus on reasoning. Yes. This is a pathetic error that schools have neglected for generation after generation. Only solving equations and checking answers given in the book stagnates the flow of the applications of circuit theory in real projects. Rather, try to handle the equipments—which are safer to deal with. Check circuit project tutorial and join expert electronics forum for help.  Present your finding verbally.

  • Traditional classrooms do little to brush up your analytical skills. So as long as you have to stick to your on-campus course outline, you have to cultivate your reasoning for better performance. Along with your learning of basic electronics theory, etch in your studied concepts somewhere else, a slot for online discussion.
  • Practice. Not just exercising question books. Repeated practice and relating physics to everyday life. Relating the circuit theories to real world phenomenon makes perception clearer.
  • Basic Circuits Theory video tutorial also helps a great deal to absorb the Technology you’re taught in class advanced with ample illustrations and diagrams. It gives you an extra edge among your peers diving into the vast realm of electronics.

Electronics Guide to LED Flashers Circuits—for Beginners

Source: bit.ly/1GubrnR

Giving the common dim, poorly flashing headlights a miss, LED alters the mode of vehicle communications. An LED requires very little electrical current—hence this is very energy-efficient. But it dazzles brightly to a fault! Almost a passerby can stop and stare blank for a few moments, bemused by its sheer intensity. Learning electronics is easier when you have a nitty-gritty guide.

One main difference between incandescent bulbs and LED for your car is filament presence. In the traditional bulbs, electricity runs through the circuit and applies heat to tungsten filament—one for the car’s rear-light and the other is, brake-light. In LED flasher, filament is missing. Here electrical charge forms an arc, leaping across a gap. A ‘reflector’ channelizes the power to glow it up.

Source: bit.ly/1uVj1jd

How it lights up is very simple. In sharp contrast to the earlier bulbs that used to toss down a large bulk of power, the current consumed by LED immediately runs into flashers and applies heat to a switch inside, of bimetal constituent. When heat twists the shape of bimetal, it prompts the circuit to break—compelling the light to switch off. As a result, the switch in its “off” mode, cools off and turns back to its original shape. Again when you switch on the heat, the circuit is again ‘on’—recreating the cycle. Thus learn electronics always with more applications and less jargon.

Sometimes you may face a little problem with LED flashers if you don’t have sufficient amount of current delivered through the circuit. Inadequate heat bends the bimetal, without deforming them to the right amount. It may lead the signal to glow on—without optimally flashing the circuit on and off.

LEDs viewing angle is very narrow generating a focused stream of light. What happens with regular bulb, is their light disperses all way in irregular pattern, on the contrary, LED element has a light spread range of 20- ,30- degree. Therefore it hits stark light just ahead, but the light loses intensity if you’re viewing it at a bent angle. In order to get a clear radiance, place the LED point exactly towards the car’s rear; don’t keep a tail-light on an angle. Online electronics learning is oozing with fun if you have the right tutorial to guide you.

An Introduction to Power Factor Correction—for Beginners

PF (Power Factor) is a vital topic in the introductory study of AC circuit theory. Although it looks simple when you take a cursory glance, students often misunderstand the concept and apply it inappropriately without a clear understanding of the definition. Free AC circuit video tutorial can clarify our doubts on different techniques of Power Factor Correction.

By definition of PF, in an AC source, it’s the ratio of original power (measured in watts), flowing towards the load, to power which appears to flow in the circuit. So, exactly Real: Apparent. The current and voltage produce apparent power.

Why PFC Needed in Electronics Devices

Power Factor Correction definitely hits a high score in modern electronics market, and looks forward to a great future, due to a several factors– high performance, the cost of magnetic material and copper escalating higher, and the cost of semiconductor reducing. Therefore, Power Factor Correction calls attention for cost-effective, favorable electronics solutions. It enhances the efficiency and performance of a power system, compensates for basic reactive power those issues from or consumed into the loads (capacitive or inductive). The utility of PFC techniques lay in the manufacture of highly reliable, low cost electronics products with increase of “switching loads.”

Types of PFC Active Controller Chips

Basically Power factor Correction is utilized with three types of controller chip variants—according to various types of use.

Power Factor Correction Applications in Low-priced, “Switch mode” System

PFC has the potential to improve control-circuitry efficiency in major consumer electronics products—industrial to domestic. This includes DVD, TV, audio player, IT products as printers, PC, Laptop, Fax machine. Motor Drives, cooking electronics appliances as microwaves and induction cooktop, LED, and any other devices that need power conversion. It not only boosts the availability of such end-user products but also trims down electricity-usage cost at large. PFC techniques are thus made easy with Free circuit theory tutorial video that spells out different functions of AC circuit control, the various aspects of network theorem with good illustrations.

Advent of technology and how traditional schooling can survive

If the recent Digital Economy Summit panel discussion at Georgia, Atlanta is anything to go by, the technological changes are luring the people more and more and because of that, the role of teachers might get undermine din the process and it is best if they alter their roles accordingly.

Experts say that teachers are going to face a tough time soon finding a foothold in the education system and it is important they know how their relevance can be kept intact in the midst of the technological advancement. Using their skills to help students find what they need is the most profitable way they can work.

Education policy makers want to know ways of teaching using technology and several students are already resorting to online methods to study. A brand new education network is on its way to be built even though the classical mindset of a posh classroom work setting is still alive.

Much of that is to do with the internet which is providing avenues for students to know things wider than what their syllabus is covering. It is making network companies to invest more and more for homes and neighbourhood connections. Jobs are being created through technology just like what Boston Red Sox is doing with technological systems that help the Boston organization. Wielding data is also an important role the technology is undertaking.

Crowd funding is yet another use these websites are used for, raising money for business and charity work. Apparently, churches have been using crowd funding for years without giving a name to it. People are finding this an improved, better and faster way to get help regarding any aid they might need.

The panel also discussed on what is called the MakerSpace, which is an online community that helps to create and share projects in robotics, drone, 3D and printing amongst others. The panel participants questioned on knowing ways of getting the children involved and addressing important questions.

Teachers who are facing the heat due to technology, one great way to balance it out is to devise out new models for their students. Know the right tools you can sue and use them well. When technology is incorporated in the classroom it helps making it interesting for students as they learn through a tool which they already know of and enjoy. Using technology in a professional and constructive way will have a positive career impact. This will also help them improve upon things easily and get an understanding of the whole online working process.

The education system has to be reviewed and managed well in order to reach a point of sustainability for both of the aspects. Technology is here to stay, and progress with each day and students are forever going to need teachers, one way or the other. So it is important both know how to co-exist, and improve upon the education system as a whole.
