Source encoding deals with the encoding analog source signals such as speech and image signals.
Channel encoding deals with error control during the transmission through the communication channel.
Modulation is the process in which the carrier signal is modulated according to the information bits. Modulation schemes are as follows:
Physical Channel: The method of creating physical channels involves allocating the finite resources.
Digital Filters: Filters to remove the out of band components
Synchronization / Carrier Recovery: In order to demodulate the information bits the locally generated signal should be synchronized with the incoming signal.
