Every day, in our work and our leisure time, we come in contact with and use a variety of modern day communication devices and communication media, the most common being the telephone, radio, tv, and the Internet. Through these media we are able to communicate (nearly) instantaneously with people on different continents, work our daily business, and receive information about various developments and events of note that occur all around the world. E-mail and imitation transmission have made it possible to rapidly connect written emails across wonderful distances.


Information sign is given for the transmitter which then transmits the message above the medium towards the receiver. Noise gets added up to the meaning in the channel. It degrades the sent information.


It has a number of electronic elements and circuits which are designed to convert data signal into electronic indicators compatible with the medium.


It allows the transmitted message and converts it back into an understandable kind.

Communication route:

It is the moderate by which electronic signal can be sent from location for the other. Signals which have to become transmitted happen to be converted into electric and permanent magnetic fields that propagate quickly over extended distances. Likewise, the channel attenuates the signal resulting in the sign degradation. Finally the amplitude of the signal received will be much lower than original signal. Hence, the amplification of the signal should be done both in the transmitter and the receiver.


It is the unwanted electrical energy which gets added up with the information signal in the channel. Electronic. g.: Noise due to lightening i. elizabeth., from the atmosphere, Internal sound due to inner agitation of atoms in the components. Because of noise meaning may get entirely missed or misinterpreted.


To get convenience, different kinds of EM radiations happen to be classified in respect to their wavelength- or, equivalently, their frequency. The term electromagnetic spectrum is utilized collectively to spell out EM ocean of all frequencies. The desk below list most of the prevalent names utilized for EM surf in order of accelerating frequency, with approximately regularity and wavelength limit. Radio, microwaves and infrared waves are commonly used for communication.


Floor Wave Distribution

Follows contours of the globe Can Pass on considerable distances Frequencies up to 2 MHz Example: I AM radio

Heavens Wave Propagation

Signal mirrored from ionized layer of atmosphere. Signal can travel a number of hops, back and forth. Good examples SW a radio station

Line-of-Sight Distribution

Transmitting and receiving antennas should be within line of sight case in point Satellite communication Ground connection


The First Telegraph Line

The first telegraph line hooking up from the British Resident for Perak home in Kuala Kangsar towards the house of Deputy United kingdom Resident in Perak for Taiping by Department of Posts and Telegraph in 1874. This telegraph collection measured 40. 5 km and travelled across forest at Bukit Berapit, that signalled the start of the time of telecoms in Malaysia. However , during Japanese careers, the telegraph lines were nearly separated by the Western army. The Telecommunications In Malaysia
