2. 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.

3. 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.

4. 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.
