The world of electronics is all about electrical circuits, electronic components, and interconnected technologies. All these elements can be primarily categorized as digital, analog, or a combination of both. However, here we will be focusing on the basics of the analog category in detail.
Analog electronics is a branch of electronics that deals with a continuously variable signal. It’s widely used in radio and audio equipment along with other applications where signals are derived from analog sensors before being converted into digital signals for subsequent storage and processing. Although digital circuits are considered a dominant part of today’s technological world, some of the most fundamental components in a digital system are actually analog in nature.
In a world enamored with all things digital, analog just refuses to die. After all, everything we have and use today is digital. Our cameras, telephones, television, communications systems, and everything else seem to have gone digital. For instance, in electronics, it is convenient to represent numbers like 1, 2, 3, etc., using the binary system because ‘1’ and ‘0’ can be conveniently related to “ON” and “OFF.” All digital equipment – starting right from a microwave oven, washing machines, and traffic lights to calculators and computers use the binary system.
at the very lowest level, digital systems themselves run on an analog base.
No matter how “digital” the electronic devices get, they always require interfaces that translate signals from the physical world into the digital world.
So, without knowing Analog Electronics well, we can not expect to grasp the Whole electronics’ concept.
Kids will start to learn electronics from scratch. No abstract things will be fed.
