Claude Shannon and Warren Weaver were engineers at Bell Labs who developed a model of communication to maximize efficiency of telephone cables and radio waves. Their model included an information source, transmitter to encode a message, channel to transmit signals, receiver to decode the message, and destination to receive the message. Noise is a dysfunctional factor that can interfere with the message as it travels through the channel, potentially changing the received signal. The model helped establish a mathematical theory of communication and is considered foundational to the field.

 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

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.
