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.

Learning Karnaugh Map Made Easy with Digital Electronics Video Tutorials


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.

5 Best Electronics Features of Infrared Remote Fans


With modern world’s consumption of power growing more and more, Launch of a super smart home appliance that saves energy is always welcome. The newly launched super-efficient fans have a positive influence on the market for its eco-friendly appeal. Online electronics video tutorial services can enhance our learning on such electronics systems. We’d here dissect the features of “Superfan” manufactured by Indian electrical appliance company Versa Drives Pvt. Let’s take a look at its amazing features that set it apart from ordinary electric fans.

  • The secret behind the efficiency of Super-fans is that they use an electronics motor different than usual—BLDC (Brushless DC). Typical fans in earlier times consisted of single phase Electric Motor (Induction). They carried more aluminum, and less use of copper made them cheaper. But actually aluminum made it inefficient.


  • Source:

    Efficiency is determined by use of electricity. Interestingly, the electricity requirement of the fan is very low—30-35 watts. We’re talking about 50% less electricity burning than regular fans here. Most fans in the past burnt 70 Watts in average.


  • The super ceiling fans deliver almost 230 m3 per minute regular delivery of air—performance as fast as a regular ceiling fan. But unlike Versa efficient fans, they tend to be the ones with more showy, luxurious style—with more emphasis on air circulation than air delivery.


  • In the inner side, it contains a back-iron rotor made of arc segments. A video tutorial on electronics can show you the inverter and control system which is micro-control based with a motor-controlling frame ware implanted in the BLDC motor. It renders the electronics system with better protection and machine control. How it works is simple. Te controller can sense the position of rotor and ensures a reliable start. So it cuts off the necessity of an extra sensor.


  • Superfans by Versa operate in a good width of voltage range. The design is trendy and soothing on the eye. It has three variants in the market.—available in different curves, colors. It can run with or without an infrared remote control. These types, on the whole, are devised for different applications. Their performance also varies according to the room type. SuperA1 model is more suitable for hospitals, workplace, classrooms and bedrooms with least noise, and SuperX1/X7 is aimed at delivering more air in small rooms and workplaces (individual). For strong, wide air circulation in banquet halls, halls and conference room, SuperV1/V7 is a great buy.

Intel or IBM—What to Choose for Office?

Intel & IBM

Finally, the processor global race gets down to basic 3 competitors. IBM zEC12 required for high-load processing of data. Intel x86 with its phenomenal reach for desktops, laptops, small servers and medium load servers. And then, IBM Processor which has won Unix stackload where HP and Sun had previously reigned.

For common mass, small-scale business and operational activities, IMB Power and Intel x86 top the list—looking each other eye-to-eye in international chip market. Now which technology to select depends on their nature. Now let’s take a look at the technology legacy both these giant manufacturers carry with them, microprocessor video tutorial can assist you to gain a clear vision on which product would most lucrative application for your office.

  • Intel x86 is more for popular for ‘Compatibility’—while IBM Power for ‘Data and Quality Performance’

Intel’s venture in the market started with 8088, thirty two years ago to be precise. Since its arrival, Intel has structured and restructured their chip architecture with a speed beyond belief. The instruction set architecture was initially modelled as 16 bits then moved to 32 bits, finally 64 bits—this advancement of chip-technology is accompanied with higher compatibility. It operates in everything well. Mini and supercomputers alike.

IBM embarked on its journey of Power Architecture in 1997. The processor in 2001 came to be known as “Power4”. It was highly renowned for being the first in the industry for devising a multi-core processor for the first time. The design team gathered from various quarters and set up instruction architecture especially for quality data performance and razor-sharp computing process.

  • Hypervisor is the Key Difference

To keep up with today’s pace, you need to virtualise your enterprise to make your workloads swift and agile. IBM’s chief weapon is Power hypervisor. It creates minimum overhead, and high efficiency virtual input, output and CPU resources. But virtualisation Intel x86 involves various add-ons that work as third party—these of course consist of hypervisors. We can also notice that Linux operating system revolves acts using Hyper-V as an exception from Microsoft—tailored to act as a virtual entity bonding the system — hardware and I/O. It leads x86 to utilise a single server with an aid of a single application.

Online microprocessor video tutorial can boost your knowledge more on the architecture set and design of the processor chip. Which chip to select rests on the requisite workload. Needs of OS, infrastructure and scalability. If data processing is your forte or you need to maintain a colossal data warehouse, go for IBM. If your necessity revolves around Windows, pick Intel.
