basic elements of telecommunication system

transmitter

transmitter (information source) takes information , converts signal transmission. in electronics , telecommunications transmitter or radio transmitter electronic device which, aid of antenna, produces radio waves. in addition use in broadcasting, transmitters necessary component parts of many electronic devices communicate radio, such cell phones,

copper wires


transmission medium

transmission medium on signal transmitted. example, transmission medium sounds air, solids , liquids may act transmission media sound. many transmission media used communications channel. 1 of common physical medias used in networking copper wire. copper wire carry signals long distances using relatively low amounts of power.another example of physical medium optical fiber, has emerged commonly used transmission medium long-distance communications. optical fiber thin strand of glass guides light along length.

the absence of material medium in vacuum may constitute transmission medium electromagnetic waves such light , radio waves.

receiver

receiver (information sink) receives , converts signal required information. in radio communications, radio receiver electronic device receives radio waves , converts information carried them usable form. used antenna. information produced receiver may in form of sound (an audio signal), images (a video signal) or digital data.
