Facilities ranging from computers, microprocessors, medical equipment to washing machines and refrigerators are based on the principle of digital electronics. Today, there is hardly any area connected with our daily lives in which the digital system has not given its knock. Actually digital technology or digital circuits are electronics that operate on digital signals. The application areas associated with digital electronics are constantly evolving. Today the field of digital electronics, which is going to touch such heights, the main reason behind this is the invention of the integrated circuit. It is the development of IC technology that made it possible to fabricate complex digital circuits such as microprocessors, memory, etc. and the digital revolution started. The invention of the microprocessor has created a stir in the technological world. Let's test your knowledge about Digital Electronics.
