Difference Between Analog and Digital Communication

The main key difference between analog and digital communication is that analog communication uses analog signals for transmission and reception of data while digital communication uses digital signals for transmitting and receiving data. 

What is analog communication?

analog communication the data is transferred with the help of an analog signal in between the transmitter and receiver. Any type of data is transferred in the analog signal. Any data is converted into electric form first and after that, it is passed through a communication channel. analog communication uses a continuous signal which varies in amplitude, phase, or some other property with time in proportion to that of a variable.

What is digital communication?

Digital communication is the one that uses digital signals for transmitting information between source and destination. Digital signals are represented by a square wave. This signal consists of discrete values rather than a continuous signal of values.

Difference between Analog and digital communication:

  • In analog communication, the analog signal is used for information transmission, while a digital communication digital signal is used for information transmission.
  • Analog communication signals use analog signals whose amplitude varies continuously from time from 0 to 100, while digital communication uses digital signals whose amplitude is of two levels either low level 0 or either high level 1.
  • Analog communication system gets affected by noise highly during transmission through a communication channel, while digital communication gets affected by totally noiseless during transmission through a communication channel.
  • In Analog communication only a few channels can be broadcasted simultaneously. While digital communication can broadcast a large number of channels simultaneously.
  • Analog communication noise immunity is poor, but digital communication noise immunity is good.
  • Analog communication coding is not possible, while digital communication coding is possible. Different coding techniques can be used to detect and correct some errors.
  • In Analog communication error probability is high, while the digital communication error probability is low.
  • Some synchronization problem is there in analog communication, while the digital communication synchronization problem is easier.
  • Analog communication systems are having complex hardware and less flexible, while digital communication is having less complex hardware and more flexible.
  • Analog communication separating noise and signal in analog communication is not possible, while digital communication separating out noise and signal in digital communication is possible.
  • Analog communication is less portable, while digital communication portability is high.
  • Analog communication system is a low cost, while the digital communication system is high cost.
  • Analog communication for multiplexing frequency division multiplexing is used, while the digital communication for multiplexing, while the digital communication for multiplexing time-division multiplexing is used.
  • Analog communication is required low bandwidth, while digital communication systems require high bandwidth.
  • Analog communication power consumption is high, while power consumption is low in digital communication.
  • Analog communication has no privacy is less so not highly secured, while digital communication privacy is high so it is highly secured.
  • Analog communication not assures an accurate data transmission, while digital communication assures a more accurate data transmission.
