Electronics and telecom engineering are the parallel linked engineering fields. Development of the electronic and telecom is rapidly increasing with culture and their application in daily life. Electronic engineering is the development, designing, application of the circuits, devices, information systems and soon. Telecommunication engineering that work on transmission, reception of messages and data. These engineering that helps the development of television, radio, telephones and soon. These engineers design the circuits to perform the amplifying electronic systems, binary numbers and demodulating the radio signals and send them by the wave forms to the television, telecommunication devices and soon. These techniques are also useful in implementing in the agriculture, oil, energy and soon. This is the challenging profession and it includes supervision, manufacturing, installing and maintaining the devices.
