Digital electronics is a field of electronics involving the study of digital signals and the engineering of devices that use or produce them. This is in contrast to analog electronics and analog signals. Complex devices may have simple electronic representations of Boolean logic functions.
Digital electronics are electric circuits that work on only two fixed values: “1” and “0”. They use a series of 1’s and 0’s to store and communicate information. They can also perform math using just 1’s and 0’s. This is called Boolean math or Boolean logic.
Digital Electronics is very important in today’s life because if digital circuits compared to analog circuits are that signals represented digitally can be transmitted without degradation due to noise. Also in digital system information stored is easier than that of analog system.

Many of our household items make use of digital electronics. This could include laptops, televisions, remote controls and other entertainment systems, to kitchen appliances like dishwashers and washing machines. Computers are one of the most complex examples and will make use of numerous, complex circuits.
Electronics has branches as follows: Digital electronics . Analogue electronics. Microelectronics. Circuit design. Integrated circuits . Power electronics. Optoelectronics. Semiconductor devices.
a smartphone is a digital system that has software (apps, an operating system), input components (for example, touch screen, keyboard, camera and microphone), output components (for example, screen and speakers), memory components (for example, silicon chips, solid state drives), communication components (for example,
Digital circuits use transistors to create logic gates in order to perform Boolean logic. This logic is the foundation of digital electronics and computer processing. Digital circuits are less susceptible to noise or degradation in quality than analog circuits .
Digital Logic is hard . Like, if-you-pass-with-a-C-you-should-be-happy hard , but it is not impossible. Every single embedded system you use, from an Ipod to an Xbox was designed using the fundamentals of digital logic you are learning right now.
Digital signals are a more reliable form of transmitting information because an error in the amplitude or frequency value would have to be very large in order to cause a jump to a different value. Signals are composed of infinite possible values. They also can be used to store information and data.
Advantages of Digital Communication The effect of distortion, noise, and interference is much less in digital signals as they are less affected. Digital circuits are more reliable. Digital circuits are easy to design and cheaper than analog circuits .
Digital signals must have a finite set of possible values. That’s the big difference between analog and digital waves. Analog waves are smooth and continuous, digital waves are stepping, square, and discrete.
The basic logic gates are classified into seven types: AND gate, OR gate, XOR gate , NAND gate , NOR gate , XNOR gate , and NOT gate . The truth table is used to show the logic gate function. All the logic gates have two inputs except the NOT gate , which has only one input.
Analog Circuits and Digital Circuits is a classic way of differentiating between two types of electronic circuits based on the signals they process. To put it in simple words, Analog Circuits deals with continuous analog signals whereas Digital Circuits deals with discrete digital signals.
