After transmission, the signal is received at some other point where the message is decoded and forwarded to the end user which may be either a human being or some device. This representation is characteristic of the usual communication system in which the signal channel is either a path through which a radio wave propagates such as the troposphere or ionosphere surrounding the earth, or a pair of wires such as in telephone transmission, or a coaxial cable as in closed circuit television and normally is the place at which interference is coupled into the system.
