Basic Block Diagram of A Communication System
The System is composed of the following functional Blocks:
The Transmitter- where this process here includes encoding,compression and error correcting operations,modulation process if some type of carrier to be used.
The Channel
where this refers to the available media like transmission lines,fiber cables,the radio frequency spectrum over which the information coming from a transmitter actually propagates or travels to a particular receiver.
The Receiver
- where the receiver performs the processes: decoding,decompressing,comparing error correction codes,demodulating the radio signal to seperate it from any carrier that was used.
The Noise
the noise is generally normal in communication process.we cannot prevent it but we can minimize it. when you say noise this is unwanted form of a signal that disturbs ,interferes and affects the wanted signal in the communication process.
