Introduction to Digital Electronics

Modern technology is collaborating with Digital Electronics to simplify our lives. According to a layman, Digital Electronics are our everyday utility items, such as remote control, laptop, smartphone, dishwasher, and more. The most complex Digital Electronics is the computer.

However, for design engineers and electronics engineers, Digital Electronics is beyond appliances. The term Digital Electronics branches out from engineering devices that require the study of circuits, electronics, and digital signals.   It is a chain of digital operations put through a series of successive operations by electrical switching circuits to accomplish logical designs.

The contribution of Joseph Henry’s invention of the electronic circuit or electronic gate in 1835, the world is gradually moving towards the digital age. The invention gave birth to several gadgets and electronic devices. The microprocessors and Integrated circuits are the best results of digital electronics.

Digital Electronics is a broad concept, which deals with digital systems and signals. Science students study Digital Electronics to understand the working of semiconductor chips and devices, such as Photocell, Diode, Phototransistor, etc. Students must grasp the fundamentals of Digital Electronics to understand the concept of a digital system.
