Communication is the process of exchanging information. It is the process of stablishing link between two points for information exchange.
The electronic equipment used for communication purpose are known as communication equipment. These communication equipment are assembled togather to form a communication system.
Examples: line telephony , line telegraphy , mobile communication , radio broadcast ,tv broadcast etc.
Communication System Elements :
1. Information Source:The source which generate useful information is termed as information source.
2. Transducer: It is a device which is used to convert one form of energy to other form. We can say that it converts information signal into electrical pulses. For example microphone converts sound waves into electrical signals.
3. Transmitter : In this signal processing is done so as the signal can be transmitted easily and safely. In this amplification and modulation of signal takes place.
4. Channel: It is the medium through which information travels from transmitter to reciever. It can be wirelines , microwave links , optical fibre cables etc.
5. Reciever: It is used to reproduce the signal in original form. The reproduction of signal is done with the help of demodulation.
