Analog vs. Digital: A Comparative Study is more Effective with Video Tutorials


I know well that most of my readers who are in Electronics study face somewhere lost in their course when it comes to the question of understanding the core functioning of Digital Circuits. Especially when it’s about deciphering the oppositions of Analog to Digital circuits, the brain gets more twisted like a circuit than ever before.

When such is the case, a live video tutorial is essentially helpful as it can minimize the pain involved in understanding the crucial functioning of Logic Gates, different variable of Karnaugh Maps or CMOS. An affordable subscription to the video tutorial packages can render value to your Electronics learning.

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.



Signal Analog signal is built with constant signal which represents physical measurements Digital signals are distinct time signals produced by digital modulation
Waves Signified by sine waves Signified by square waves
Representation Uses continuous series of values to indicate information Uses discrete or irregular values to indicate information
Technology Analog technology accounts waveforms as they are Illustrates analog waveforms into a partial set of numbers and accounts them
Data transmissions Subjected to decline by noise throughout transmission and write/read cycle Can be noise-resistant without decline throughout transmission and write/read cycle
Response to Noise More possible to get affected dropping accurateness Less affected given that noise response are analog in character

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.

10 Ways to Have a Grand Home Theatre Experience


Your TV Experience sucks. Thanks to bunch of cables, huge boxes, poorly-handled connections, endless outputs, input that you have no idea how to deal with. It’s a dreaded job each time to call up for help and snub-nosed mechanics that don’t show up for such “petty issues”.

But, to tell you the truth, it’s no giant work. Home theatre set-up is easier when you have a glimpse of guidelines by digital Electronics video tutorial to check if everything’s well-connected so that your channels runs smooth and you make the most of the system. Do away with the hassles and optimize your cinema experience.

Speaker Positions Simple Guidelines

Follow our electronics tutorial to position your speakers strategically to have the best home theatre experience.

  • Source:

    If you want the best sound quality, understand the position and role ideally assigned to each speaker. Select the centre of room.

  • Position the speaker’s angles at this focal point. If you’re sitting, the height of the Front Right and left speakers should be kept in ear’s level—45 degree angle form the central seat. It widens the range of sound, surrounding you with the thrill of the big screen.
  • Centre Channel Speaker should be placed either below the display or above.
  • Surround Right/Left speakers should be kept at least 2 and a half feet higher than the viewer. This covers the room with strong special effects.
  • If you have several Sub-woofers, place them on the walls—exactly at the middle. And if you have only one Sub, hang it on the front wall—the screen direction.

Tune Speakers to Boost Sound

Even if you follow the rules mentioned above, you may not get the best of what your speakers might offer. Because, one room may not be similar to the other.

  • You have to give it a listen quite a few times to familiarize with the speakers position, angles and height.
  • Online Electronics video tutorials would suggest you to experiment by repositioning to enhance the sound kick of a home theatre.

Clear Way

  • Make sure that no piece of furniture blocks the path between the centre viewer’s seat and the speakers. The path should be unobstructed.
  • Keep the walls dark to have a rich visual delight. Keeping walls dark and windowless would make you real room fade into black when you dive in the cinema world.
  • Acoustic panels to soundproof the room can give a groovy sound quality completely obliterating the noise and commotion from the world outside. In addition, your neighbours would not complain!

So, pamper your senses with the chill of booming sound system and keep checking electronics video tutorials for more fun stuff. Happy movie-time!
