Digital Electronics & Its Advantages And Disadvantages

Digital electronics are the systems that use a digital signal instead of an analog signal. The Digital Electronic circuits operate with digital signals. They are discrete signals sampled from the analog signal. These circuits use binary notation for transmission of signal. Digital circuits are constructed from small electronic circuits called logic gates and they are used in creation of logic combination. Each of these logic gate is built to perform a function of Boolean logic when acting on logic signals.

Why computer Engineers need to know about Digital System Electronics

Computer science and engineering has several fields of electrical engineering and it required to form computer hardware and software. Computer engineers have training in electronic engineering, software design, and hardware-software integration instead having training only on software engineering or electronic engineering. Computer engineers participate in different hardware and software factors of computing ranging from the design of individual micro-controllers, microprocessors, personal computers, and supercomputers, to circuit design.



Digital electronics uses VLSI technology, which has greatly decreased the size and area of the circuit boards and has also enhanced the accuracy and performance of the systems. Although Mostly, these digital systems have the advantage of data encryption for communication purposes. The data transmission is very safe and secure. All these factors mentioned clearly show that the digital electronic stream has wide future scope in the modern era.

Advantages Of Digital Electronics

They are relatively easy to design.

Higher precision rate in terms of accuracy.

The Transmitted signals are not lost over long distance.

Digital Signals can be stored easily.

They are more immune to 'error' and 'noise' than analog. But in case of high-speed designs, a small noise can induce error in the signal.

The voltage at any point in a Digital Circuit can be either high or low; hence less chance of confusion.



Flexibility that has ability to change the functionality of digital circuits by making changes in software instead of changing actual circuit.

Disadvantages of Digital Electronics

The real world is analog in nature, all quantities such as light, temperature, sound etc. Digital Systems are required to translate a continuous signal to discrete which leads to small quantization errors. To reduce quantization errors a large amount of data needs to be stored in Digital Circuit.

Digital Circuits operate with digital signals only hence, encoders and decoders are required for the process. This increases the cost of equipment.
