History of electronic
engineering
The
history of electronic engineering is a long one.[citation needed] 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".[1]
Electronic
engineering be used 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.[2] 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[3] In the late 1950s the term electronic engineering started to
emerge.[4]
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.[5][6] 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.
