Following are the difference between analog communication and digital communication:
|| Digital communication
|Analog communication is converted original information into equivalent analog signal.
|| Digital communication is converted original information into equivalent digital signal.
|In analog communication the coding is not possible.
||In digital communication the coding techniques used to detect and correct the errors.
|It has poor noise immunity.
||It has excellent noise immunity.
|In analog communication, the signal can take up voltage level corresponding to any real number,
||In digital communication signal can take up only one among two voltage levels corresponding to 1 and 0.
|It is not appropriate for secret transmission such as military, police etc.
||Because of coding techniques it suitable for police military etc.
|It required less bandwidth.
||It required more bandwidth.
|FDM is used for multiplexing.
||TDM is used for multiplexing.
