History of electronic engineering
This article details the history of electronics engineering. 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 laboratories (Bell Labs, 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. The electronics industry was revolutionized by the inventions of the first transistor in 1948, the integrated circuit chip in 1959,[5][6] and the silicon MOSFET (metal–oxide–semiconductor field-effect transistor) in 1959.[7][8] In the UK, the subject of electronics 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 electronics engineering could be aligned, although the similarities in subjects covered (except mathematics and electromagnetism) lasted only for the first year of three-year courses.)
Electronics engineering (even before it acquired the name) facilitated the development of many technologies including wireless telegraphy, radio, television, radar, computers, and microprocessors.
Wireless telegraphy and radio
Some of the devices which would enable
In 1904,
The invention of the triode amplifier, generator, and detector made audio communication by radio practical. (
The first known radio news program was broadcast 31 August 1920 by station 8MK, the unlicensed predecessor of WWJ (AM) in Detroit, Michigan. Regular wireless broadcasts for entertainment commenced in 1922 from the Marconi Research Centre at Writtle near Chelmsford, England. The station was known as 2MT and was followed by 2LO broadcasting from Strand, London.
While some early radios used some type of amplification through electric current or battery, through the mid-1920s the most common type of receiver was the
Vacuum tubes remained the preferred amplifying device for 40 years, until researchers working for
Before the invention of the integrated circuit in 1959, electronic circuits were constructed from discrete components that could be manipulated by hand. These non-integrated circuits consumed much space and power, were prone to failure and were limited in speed although they are still common in simple applications. By contrast, integrated circuits packed a large number — often millions — of tiny electrical components, mainly transistors, into a small chip around the size of a coin.[18]
Television
In 1927, Philo Farnsworth made the first public demonstration of a purely electronic television.[19] During the 1930s, several countries began broadcasting, and after World War II it spread to millions of receivers, eventually worldwide. Ever since then, electronics have been fully present in television devices.
Modern televisions and video displays have evolved from bulky electron tube technology to use more compact devices, such as
Radar and radio location
During World War II, many efforts were expended in the electronic location of enemy targets and aircraft. These included radio beam guidance of bombers, electronic counter measures, early radar systems, etc. During this time, very little if any effort was expended on consumer electronics developments.[21]
Transistors and integrated circuits
The first working
The first integrated circuits were the hybrid integrated circuit invented by Jack Kilby at Texas Instruments in 1958, and the monolithic integrated circuit chip invented by Robert Noyce at Fairchild Semiconductor in 1959.[26]
The
The MOSFET made it possible to build
Computers
A computer is a programmable machine that receives input, stores and manipulates data, and provides output in a useful format.
Although mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century (1940–1945). These were the size of a large room, consuming as much power as several hundred modern personal computers (PCs). Modern computers based on
The ability to store and execute lists of instructions called programs makes computers extremely versatile, distinguishing them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers ranging from a netbook to a supercomputer are all able to perform the same computational tasks, given enough time and storage capacity.
Microprocessors
By 1964, MOS chips had reached higher
The first multi-chip microprocessors, the
