Telecommunication is the process that is linked with the transmission of waves and signals over a distance for the purpose of communication. If we will have a look at the ancient times, telecommunication had a strong influence with the usage of signals flags or heliograph as a means of communication.

But in this current high-tech era, the term telecommunication denotes highly advanced gadgets that generally indicates the use of electronic transmitters such as the telephone, mobile phones television, radio or Internet!

Telephone was invented by Alexander Graham Bell. Other who are involved in the discovery of communication devices are Guglielmo Marconi and John Logie Baird, who hold a very important role in the field of telecommunication.

Now, the process plays an immensely vital role in the enhancement of world economy as if we will have a look at the statistics, we will notice that the telecommunication industry's contribution was estimated to be $1.2 trillion in the year 2006.

A basic telecommunication system consists of three elements:

• A transmitter that takes information and is responsible for converting into a detectable signal.
• The second process involves a transmission medium that carries the signal.
• A receiver that receives the signal and then again transforms it back into usable information.
