Expert Answer:

An analog communication system is that in which the information to be transmitted is in form of a analog signal. Analog signals are continuous variation of voltage or current, generally expressed in terms of a sine or cosine functions. They are single valued functions of time. Radio broadcast and telephonic communication system are example of analog communication systems.

            A digital communication system uses digital signals after properly coding them. Digital signals are those which can take only discrete stepwise values. Binary system is an example of digitalized signals. The digital communication applies coding system, which involves suitable combination of number systems.
