The
history of electronic engineering is a long one. Chambers Twentieth Century
Dictionary (1972) defines electronics as "The science and technology of
the conduction of electricity in a vacuum, a gas, or a semiconductor, and
devices based thereon".
Electronic
engineering as a profession sprang from technological improvements in the
telegraph industry during the late 19th century and in the radio and telephone
industries during the early 20th century. People gravitated to radio, attracted
by the technical fascination it inspired, first in receiving and then in
transmitting. Many who went into broadcasting in the 1920s had become
"amateurs" in the period before World War I. The modern discipline of
electronic engineering was to a large extent born out of telephone-, radio-,
and television-equipment development and the large amount of electronic-systems
development during World War II of radar, sonar, communication systems, and
advanced munitions and weapon systems. In the interwar years, the subject was
known as radio engineering. The word electronics began to be used in the 1940s
In the late 1950s the term electronic engineering started to emerge.
The
electronic laboratories (Bell Labs in the United States for instance) created
and subsidized by large corporations in the industries of radio, television,
and telephone equipment, began churning out a series of electronic advances. In
1948 came the transistor and in 1960 the integrated circuit, which would
revolutionize the electronic industry. In the UK, the subject of electronic
engineering became distinct from electrical engineering as a university-degree
subject around 1960. (Before this time, students of electronics and related
subjects like radio and telecommunications had to enroll in the electrical
engineering department of the university as no university had departments of
electronics. Electrical engineering was the nearest subject with which electronic
engineering could be aligned, although the similarities in subjects covered
(except mathematics and electromagnetism) lasted only for the first year of
three-year courses.)
Electronic
engineering (even before it acquired the name) facilitated the development of
many technologies including wireless telegraphy, radio, television, radar,
computers and microprocessors.
