Advantages of Digital Systems

1) Devices used in digital circuits generally operate in one of two units, known as ON and OFF, resulting in a very simple operation.
2) There are only a few basic operations in digital circuits that are very easy to understand.
3) Digital techniques require Boolean algebra, which is very simple and easy to learn.
4) Digital circuits require basic electrical network analysis concepts that can be learned easily. The main electrical characteristics required are switching speed and load considerations. On the other hand, analog circuits and systems involve frequency and time domain concepts, complicated circuit analysis techniques, etc. which makes understanding these circuits much more difficult than digital circuits.
5) A large number of integrated circuits are available to perform various operations. These are highly reliable, accurate and small in size and the speed of operation is very high. Various programmable ICs are also available.
6) Various ICs are available in a logic family with similar electrical characteristics which greatly simplify the design and development of digital systems and also reduce interface problems. In addition, several logic families based on different technologies are available to help optimize system design in terms of power requirements and speed of operation.
7) The effect of fluctuations in component characteristics, aging of
components, temperature and noise, etc. is very small in digital circuits.
8) Digital circuits have memory capacity, which makes them very suitable for computers, calculators, watches, telephones, etc.
9) The display of data and other information is very convenient, accurate and elegant using digital techniques.
10) Many students have the opportunity to learn how to program digital computers, so they are strongly motivated to study the way digital hardware works.
11) It is a very fascinating and challenging field of study because most of the latest electronic systems are digital in nature.
