Theory Communication
The fundamental problem of communication is that of reproducing at
one point either exactly or approximately a message selected at another
point. Frequently the messages have mea&g; that is they refer to or are
correlated according to some system with certain physical or conceptual
entities. These semantic aspects of communication are irrelevant to the
engineering problem. The significant aspect is that the actual message is
one selected from a set of possible messages. The system must be designed
to operate for each possible selection, not just the one which will actually
be chosen since this is unknown at the time of design.
