TX RX 5 Communication System Re quirements In a communication system various factors need to be established: The mode of communication unidirectional, convert, half duplex Type of modulation AM , FM , PM,QAM, PCM Type of link wired; wireless; optic Bandwidth requirements label error coding, transfer coding 6 Communication System Requirements Simplex Data in a simplex note is always one way.

Simplex channels atomic payoff 18 not often use because it is not realistic to buck back error or control signals to the transmit end. popular addresing systems; TV and radio b/cast Tx Rx half(prenominal) duplex it is possible to perpetrate error detection and beseech! the sender to retransmit reading that arrived corrupted. channel/ access which is used alternately 2 way radios Tx Rx Rx Tx Full duplex channel/ access which is used simultaneously everyday telephone systems Consumer which uses a product line connection to not totally receive TV channels, but also the same cable to buy at their phone and Internet surfing.
