The cJtannel is merely the medium used to transmit the signal lrom transmitter to receiver. It may be a pair of wires, a coaxial cable, a band of radio frequencies, a beam of light, etc. 4. The receiver ordinarily performs the inverse operation of that done by the transmitter, reconstructing the message from the signal. S. The destinatiolt is the person (or thing) for whom the message is intended. We wish to consider certain general problems involving communication systems. To do this it is first necessary to represent the various elements involved as mathematical entities, suitably idealized from their physical counterparts.

For each state only certain symbols from the set S. , · · · , S" can be transmitted (different subsets for the different states). When one of these has been transmitted the state changes to a new state depending both on the old state and the particular symbol transmitted. The telegraph case is a simple example of this. There are two states depending on whether or not + + + + + C. E. Shannon 10 a space was the last symbol transmitted. If so then only a dot or a dash can be sent' next and the state always changes.
