applications of digital systems?

Question

i want the application areas of digital electronics for my assignment.

Answer 1

Digital systems are those electronic systems that use a digital signal instead of an analog signal. Digital electronics are the most common representation of Boolean algebra and are the basis of all digital circuits for computers, mobile phones, and numerous other consumer products.
Applications:
cellular telephones
audio systems
clocks
computer
etc

Answer 2

Depends how you define reliable. In the strictest sense, digital applications are less reliable than analogue. A glitch on the power going to a digital computer will cause the computer to crash. You need to come along and manually restart it. In contrast an analogue computer in the same scenario would just keep going. You might see a small spike on the ouptut, but that's it. Digital computers also have a lower Mean Time between failure (MTBF) than an analogue computer designed to complete the same task. This is becasue the digital computer contains many millions more transistors than the analogue. Digital computers are more flexible and more precise than their analogue counterparts, but that's not what the question asks.
