2. What is telecommunication?
•The transmission of information
that allows for communication
between people who are separated
by distance.
3. Examples of
Telecommunication :
•telephone system
•satellitecommunication system
•mobile cellular system
•radar and sonar systems
•microwave radio systems
•TV and radio broadcasting systems
•space discovery using telecommunications
•oil exploration using radio frequency
analysis warfare communications
•information and intelligent gathering
4. Three units of telecommunication:
A) A transmitter that takes
information and converts it to a
signal.
B) A transmission medium, also
called the “physical channel” that
carries the signal.
C) A receiver that takes the signal
from the channel and converts it
back into usable information.
5. Basic Elements of
Telecommunication
Sender
•who uses a transmitter which converts
the message into a signal.
Transmitter
• transmits the information through a
medium to the receiver which transmits
the signals into information that can be
used and understood by people.
6. Transmission medium
• carries the signal
Sender
•receives the signal and converts it back
into usable information
Channel
• responsible to transfer the information
from the source to the destination without
distortion or loss of information. Channels
tend to be affected by external signals or
noise. To achieve this a variety of
"protocols" or rules are used.
7. Telecommunication network
• represent all the players that make
telecommunication possible, from the
transmitters and receivers to the
communication mediums that make it
possible for the messages to be
transmitted.
Telecommunication medium
•refersto the channel that carries the signal
between a transmitter and a receiver.
Examples of telecommunication media in
our modern times are optical fibre as well
as cables.
