There can be a possibility of miscommunication if a user doesn't understand something.Digital communication requires analog to digital conversion at a high rate.It is due to the higher data rate because of analog to digital conversion. The most common limitation of digital communication is that it requires more transmission bandwidth.There is a requirement for synchronization in the case of synchronous modulation.There is high power consumption in digital communication.The limitations of digital communication are listed as follows.
Now, let's see the limitations of Digital communication. Digital communication is cheaper and simpler compared to analog signals because of the advancement of IC technologies.To maintain the secrecy of information, the signal processing functions like compression and encryption are employed in digital circuits.It also facilitates us with audio conferencing by which we can talk to someone or a group of people in another location without traveling.In digital communication, to avoid signal jamming, the spread spectrum technique is used.The implementation of hardware is more flexible in digital communication.The probability of cross-talk is very less in digital communication.There is a common encoding technique in most digital circuits, so for a number of processes, similar devices can be used.In digital signals, the configuring process is easy as compared to analog signals.As compared to analog signals, it is easy to save and retrieve digital signals.The correction and detection of errors are easy in digital communication, as there is a use of channel coding.It is easy to implement, less expensive.In video conferencing, we can see the facial expressions, which are helpful in reading the reaction of people.
We can perform video conferencing with someone or a group of people without any traveling.
