3. Biography
Claude Shannon and Warren Weaver were
•
•
engineers working for Bell Telephone Labs in the
United States , both of them joined together to
write an article in “Bell System Technical Journal”
called “ Shannon and weaver model of
communication”
Their goal was to ensure the maximum efficiency
of telephone cables and radio waves.
They developed a model of communication which
was intended to assist in developing a
mathematical theory of communication.
Claude Shannon (1916-2001) is considered one
of the founding fathers of the communications
age.
Shannon and Weaver model of communication
has been called the “mother of all the models”
5. Elements of the model
Information source – which produces a message
Transmitter- which encodes the message into
signals
Channel- which signals adapted for transmission
Receiver- which decodes the message from the
signal
Destination- where the message arrives
6. Dysfunctional Factor
The sixth element is the noise is an
dysfunctional factor
any interference with the message
travelling along the channel which may lead to
the signal received being different from that
send.
7. Three other factors that afffecting
while communicating
Physical noise/ Channel noise
Semantic noise
Feedback
Noise also interferes with „FIDELITY‟
8. Levels of problems in the analysis of
communication
Technical Problem
Semantic Problem
Effectiveness Problem
9. Examples
For the telephone;
the channel is a wire,
the signal is an electrical current in it, and
the transmitter and receiver are the telephone
handsets.
Noise would include crackling from the wire.
In conversation, my mouth is the transmitter,
the signal is the sound waves, and your ear is
the receiver. Noise would include any
distraction you might experience as I speak.
