Advantages of digital circuits over analog circuits

What are the advantages of the digital circuits over the analog circuits?

  • The Digital circuit is very accurate.
  • The Digital circuit generates a digital signal which is more reliable than analog signals.
  • Compare to the analog circuits is that signal represented digitally can be transmitted without degradation due to noise. 
  • Digital signal can be used by digital circuit components, which are very cheap and easy to produce in many components on a single chip.
  • Enables transmission of signal over a long distance.
  • Digital signal maintains its quality over long distances better than analog signals.
  • Digital signals carry more information per second than analog signals circuit.
  • Digital signal is used to construct a digital circuit since the cost of digital components is very cheap.
  • Digital circuits are easy to design and cheaper than analog circuits.
  • Digital signal faster than the analog signal.
  • The hardware implementation in a digital circuit is more flexible than analog.
  • In a digital system, a more precise representation of a signal can be obtained by using a binary digit(0's or 1's) to represent it. Each digit handled by the same kind of hardware.
  • The signal processing function such as encryption and compression are employed in digital circuits to maintain the secrecy of the information.
