The document discusses the fundamentals of telecommunication, which involves the transfer of information over distances. It outlines the elements of a basic communication system including input transducer, transmitter, communication channel, receiver, and output transducer while also touching on the history and development of communication technologies. Additionally, it addresses the impact of noise on signal transmission.

2.  INTRODUCTION
Telecommunication means communicating at a
distance. a communication system is a means of
conveying information from one place to another
place. This information can be of different types
such as sound pictures,music etc.

3.  HISTORY
The field of communication engine started
developing rapidly in 19th century which the
telegraph , telephone and then radio were
invented. The development was still faster in
20th century.

5.  ELEMENTS OF BASIC
COMMUNICATION SYSTEM
1. Input transducer.
2. Transmitter.
3. Communication channel.
4. Receiver.
5. Output transducer.

6. INPUT SIGNAL
The communication system channel have been
developed for communicating useful information
from one place to another place . the
information can be in the form of a sound signal
,speech, music or picture or data information
coming from the computer.

7. 1. INPUT TRANSDUCER
The information in the form of
sounds,picture signal can not be transmitted
as it is first it has to be connected into a
suitable electrical signal the input transducer
done this job.

8. 2. TRANSMITTER
The function of transmitter block is to convert the
electrical signals to the information of a suitable
form. The transmitter consist of the electronic
circuit such as amplifier oscillator & power
amplifier.

9. 3. COMMUNICATION CHANNEL
The communication channel is the medium used
for transmission of signal from one place to
another. The communication medium can be
conducting optical fiber depending two types of
communication medium which exist they are:-
(i)wire communication
(II)wireless communication

10. NOISE
Noise is an unwanted electrical signal which gets
added to the transmitted signal when it is travelling
towards the receiver the noise can be natural or
man made . The source of natural noise one
lighting or radiation from the sum and stars etc. the
man made noise includes the noise produce by
electrical ignition system of the automobile machine
etc.

11. 4. RECIEVER
The reception is exactly the opposite
process of transmission demodulation and
connected into a suitable form the receiver
consist of electronic circuit line oscillator
amplifier etc.

12. 5. OUTPUT TRANSDUCER
It connects the electrical signal at the output
of the receiver back to the original form that
is sound, picture,video etc.
