Digital communication is a system that any message pass through digital devices. It is the ability to create communication in different media. It transmits any information by digitally. Now let us check it out a lot of advantages, so we have to know more about digital communication.
Advantages of digital communication :
- It can be done over large distances through internet devices and other things
- Digital communication technology is easy to mix signals and also have data using digital techniques
- Greater dynamic range is possible
- More option and flexibility in terms of recording and also a reviewing data
- Used in military application
- The inexpensive circuit may be used
- Digital communication gives facilities like video conferencing which save a lot of time, money as well as effort
- Digital communication is done over a large distance through the Internet and is spread almost in every cities and town. So in the compatibility of digital communication systems with the internet has opened a new area of applications
- Using data encryption, it is very useful for in a military application
- High-speed computers and powerful software design tools are available, so a digital communication system flexible
- It can be tolerated the noise interference
- The digital communication is fast, easier and cheaper
- Digital communication has excellent processing techniques are available for digital signals processing such as processing methods like image processing, video processing, data compression, channel coding and equalization etc
- Much less bulky than analog equivalent
- The error may offer to be corrected with the use of coding
- Much more options being able to share media called both socially and for business
Disadvantages of digital communication :
- High power consumption
- It has a sampling error
- Nongraceful degradation
- Bit error rate or probability of error
- Require A/D conversion at a high rate
- It requires more bandwidth as compared to an analog system
- It needs synchronization in synchronous modulation
- As the square wave is more affected by noise, that's what while communicating through channel we send sine wave but while operating on a device we use squire pulses
- Complex circuit, more sophisticated device making is also disadvantages of a digital system
- More expensive to fix when it does wrong
- It was harder to fix when it does go wrong
- Miss-communication is possible if a user doesn't understand something
