Elements of a Communication System

Introduction:

Communication system is used to conveying a message from one person to other. By means of an information is the attach which holds people jointly. A communication system is known as grouping of processors and hardware used to bring about the transfer of message through communication. This system having some elements for transfer the signal from source to destination.

I like to share this Define Second Law of Thermodynamics with you all through my article.

Communication Systems:

A communication system is known as grouping of processors and hardware used to bring about the transfer of message through communication. This process of a system allows us to take total unit.

An energy is need to start the system. The control mechanism regulates the process. That is, it manipulates the message input into whatever form is necessary. The result of this method is the appearance of message in a form which will permit us for communication to take place.

Having problem with Equation for Angular Acceleration keep reading my upcoming posts, i will try to help you.

Elements of communication systems

Let us see about elements of communication systems,

Transmitter:

It is used for modulation and coding the original signal.
In communication system elements, it is used to converting an electrical signal into a form which is comfort for transmission on the physical channel or transmission medium.


Channel:

In communication system elements, the communications channel is known as a communication medium.
It is used to send the signal from the transmitter to the receiver.
The Receiver:

In communication system elements, It is used for demodulation such as decoding the signal from channel.
The receiver is used to recover the message signal enclosed in the received signal.
Noise:

In communication system elements, noise is produced at transmitter due to two process
1. Natural resources 2. Manmade

By nature, such as radiation from sun By manmade, noise made from like vehicles.
This noise can be reduced by using filter.
