Electronic Engineering is dedicated to
the study of devices, circuits and systems,
including analysis, design, development and
operation, as well as the study of the principles
on which it is based. Such devices, circuits and
systems can be used in a varied range of
applications, including, among others, digital
systems, communication systems, automation
systems and control, transportation systems
and countless personal and household
appliances, which make easier and more
enjoyable our lives.
In 1884 Thomas Alva Edison in its work to improve the incandescent
lamp detected the thermionic phenomenon, a phenomenon that bears his name. This would lead to
the first electronic valve (or electronic bulb) and the birth of the new engineering. This was the first
valve diode
In 1893, Nikola Tesla made the first public demonstration of radio
communication. In 1912, Edwin Armstrong develops regenerative
circuit, the Armstrong oscillator and the superheterodyne
receiver.
Experiments carried out by different scientists in
the late nineteenth and early twentieth century in
terms of electrical and electromagnetic
phenomena were laying the groundwork for
what would soon after a new specialty, first of
physics, and then engineering .
In 1907 Lee de Forest trying to perfect telegraph receiver added a grid between the cathode and anode of a
diode. This addition could control the current passing between the plates of primitive diode, the new element
was called triode and was the basis of modern electronics. Until the birth of the transistors, and even
much later, have been used thermionic valves for electronic circuits.
In 1947, William Bradford Shockley with John Bardeen and Walter Houser Brattain developed the transistor, at Bell Labs. This, more versatile,
economical and small device would eventually replace the valves in virtually all electronic
applications, except in audio applications of high power and high fidelity. The birth of the
transistor, in the late 50s of the twentieth century came to revolutionize electronics. In the third
phase of development we have the technology integrated circuit (chip), initially based on bipolar transistors and later in the MOSFET
transistors.
The technology development materials and manufacturing processes of semiconductor devices (Microelectronics), allowed achieve high scales of integration and increase the
flexibility and versatility of electronic devices. This allowed expand the scale of production of electronic systems and the range of products,
while reducing the cost of equipment purchased by it.

The electronic engineer has a wide range of possibilities for the exercise of
their profession. Among the companies that will require they include:
Public companies and privatecommunications; Telephones, television, data transmission, broadcasting, radar, satellites, mobile communications, etc.
Basic industry of the state, and / or production of goods and services; industrial automation and process
control.
Financial institutions: Telematics. Medical supply
companies.
Oil Industry: Telematics, communication, control,
and instrumentation.
