State any two advantages and disadvantages of digital communication system.

1 Answer

Answer :

Advantages of digital communication

 Digital signals are better suited than analog signals for procession and combining using technique called multiplexing.

 Digital transmission systems are more resistant to analog systems to additive noise because they use signal regeneration rather than signal amplification.

 Digital signals are simpler to measure and evaluate than analog signals.

 In digital systems transmission errors can be corrected and detected more accurately.

 Using data encryption only permuted receivers can be allowed to detect the transmission data.

 Wide dynamic range.

 Because of the advances of IC technologies and high speed computers, digital communication systems are simpler and cheaper.

 Digital communication is adaptive to other advance branches of data processing such as digital.

Disadvantages of Digital Communication

 The transmission of digitally encoded analog signals requires significantly more bandwidth.

 Digital transmission requires precise time synchronization between the clocks in the transmitter and receiver.
