It encompasses a range of issues in the electronics and RF industry, from design through to product implementation. The features are contributed by engineers and academics in

54-586: A merger with The Radio Review , a monthly journal that had first been published in London in October 1919. With the same issue, publication frequency of Wireless World became weekly. It was also aimed at home constructors, publishing articles on building radio receivers and, after the BBC started regular 405-line TV programmes from Alexandra Palace in 1936, complete details on building your own TV set - including

81-685: The European Commission in 2002. John Linsley Hood John Laurence Linsley-Hood (9 February 1925 in Wandsworth , London – 11 March 2004 in Taunton , Somerset ) was an English electronics engineer and designer of audio components. He was educated at Reading School , Acton Polytechnic , the Royal Technical College (Glasgow) and after World War Two, at Reading University . In 1942 Linsley-Hood joined

108-618: The G.E.C. Research Laboratories at Wembley, working on magnetron development as junior member of a team. Joining the RAF aircrew in 1943, he was transferred to work on radar , then subsequently worked with T.R.E. (Malvern) overseas. After returning to university, Linsley-Hood joined the Windscale Research Laboratories of the Atomic Energy Authority . He was in charge of the electronics team in

135-618: The electronics industry . The circulation is split between electronic design engineers, senior managers, and R&D professionals within areas such as communications, manufacturing, education and training, IT, medical, power, oil and gas. The Marconi Company published the first issue of the journal The Marconigraph in April 1911. This monthly magazine was the first significant journal dedicated to wireless communication, and it circulated largely among Marconi engineers and operators. In April 1913, after two years and 24 issues, The Marconigraph

162-580: The "editress of 2011" that would not be acceptable today. Pat Hawker MBE, also well known for the "Technical Topics" feature he authored for exactly 50 years in the Radio Society of Great Britain's "Radio Communication" or "RadCom" magazine, contributed the regular column "World of Amateur Radio" from May 1969 to April 1982. An occasional contributor, Ivor Catt , sparked controversy with an article on electromagnetism in December 1978 by challenging

189-399: The 'Tobey-Dinsdale Amplifier' and the ' Linsley Hood ' power amplifier. In the December 1975 edition an article described “feed-forward” error correction for audio amplifiers as embodied in the legendary QUAD 405 current dumping power amplifier designed by Peter Walker and M. P. Albinson. In 1975/6 Wireless World published the design of a decoder of broadcast TV Teletext information before

216-536: The 20th century and is today one of the largest global industries. Contemporary society uses a vast array of electronic devices that are built in factories operated by the industry, which are almost always partially automated. Electronic products are primarily assembled from metal–oxide–semiconductor (MOS) transistors and integrated circuits , the latter principally by photolithography and often on printed circuit boards . Circuit boards are assembled largely using surface-mount technology , which typically involves

243-555: The Research Laboratories of British Cellophane Ltd. from 1954. John Linsley-Hood is best remembered by hi-fi enthusiasts for his "Simple Class A Amplifier ", which he developed to provide a good-quality performance comparable to that of the classic Williamson amplifier . The design was published in Wireless World in 1969 (April 1969 issue, p. 148), and later updated in 1996. Linsley-Hood wrote for

270-450: The automated placement of electronic parts on circuit boards using pick-and-place machines . Surface-mount technology and pick-and-place machines make it possible to assemble large numbers of circuit boards at high speed. The industry's size, the use of toxic materials, and the difficulty of recycling have led to a series of problems with electronic waste . International regulation and environmental legislation have been developed to address

297-588: The computer industry in what is increasingly referred to as the consumerization of information technology . The CEA ( Consumer Electronics Association ) projected the value of annual consumer electronics sales in the United States to be over $ 170 billion in 2008. Global annual consumer electronic sales are expected to reach $ 2.9 trillion by 2020. Electrical waste contains hazardous, valuable, and scarce materials, and up to 60 elements can be found in complex electronics. The United States and China are

324-477: The early 20th century brought the first major consumer product, the broadcast receiver. Later products include personal computers , telephones , MP3 players , cell phones , smart phones , audio equipment , televisions , calculators , GPS automotive electronics , digital cameras and players and recorders using video media such as DVDs , VCRs or camcorders . Increasingly these products have become based on digital technologies, and have largely merged with

351-1032: The emergence of the home entertainment consumer electronics industry starting in the 1950s, largely due to the efforts of Tokyo Tsushin Kogyo (now Sony ) in successfully commercializing transistor technology for a mass market, with affordable transistor radios and then transistorized television sets . The industry employs large numbers of electronics engineers and electronics technicians to design, develop, test, manufacture, install, and repair electrical and electronic equipment such as communication equipment, medical monitoring devices, navigational equipment, and computers . Common parts manufactured are connectors, system components, cell systems, and computer accessories, and these are made of alloy steel, copper, brass, stainless steel, plastic, steel tubing, and other materials. Consumer electronics are products intended for everyday use, most often in entertainment , communications and office productivity. Radio broadcasting in

378-473: The equatorial plane orbit at an altitude of 36,000 km, spaced 120 degrees apart, could provide global communications. The altitude is crucial as there a satellite rotates at the same angular velocity as the surface of the Earth, and therefore remains above a particular point on its surface – that is, it is geostationary. The article is now seen as the origin of modern satellite communications, and

405-481: The first commercial decoder became available. Later it published regular columns of brief Circuit Ideas . In the August to December 1967 editions a series, Wireless World Digital Computer by Brian Crank, was published. It described how to build a "very" simple binary computer at home. It was constructed entirely from "reject" transistors (functional, but not meeting all specifications, consequently sold cheaply), and

432-527: The first public announcement of the Baxandall tone control circuit, a design now employed in millions of hi-fi systems including amplifiers and effects for musical instruments. In 1955 it published the design of the popular Mullard 5-10 audio amplifier using two EL84 power pentodes in ultra-linear push-pull configuration. In the 1960s and 1970s there were many further articles on advances in audio and electronic design, notably all-transistor designs including

459-505: The geostationary earth orbit is sometimes referred to as Clarke's Orbit. For decades, Wireless World was a place where pioneers in audio and electronic design shared ideas. In 1947-49, it published articles on building what became the famous " Williamson amplifier " by D.T.N Williamson - using a pair of triode-connected KT66 kinkless power tetrodes (very similar to the American 6L6 ) in push-pull to give 15 watts output. In 1952 it made

486-429: The issues. The electronics industry consists of various sectors. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $ 481 billion as of 2018. The electric power industry began in the 19th century, which led to the development of inventions such as gramaphones , radio transmitters and receivers, and television . The vacuum tube

513-529: The pen name "Cathode Ray". "Free Grid" was the pseudonym of Norman Preston Vincer-Minter (1897–1964), a classicist and ex-naval wireless operator who specialised in deflating pomposity with his biting wit. Amongst the early editors was W.T. Cocking (designer of the WW television sets); the last six editors were Tom Ivall, Philip Darrington, Frank Ogden, Martin Eccles, Phil Reed and Svetlana "Stella" Josifovska, who edited

540-424: The publication for 20 years from 2004 to August 2024. Casey Porter took over the editor role from Stella. On pages 232 and 233 of the April 1961 Golden Jubilee issue, regular contributor "Free Grid" speculates what the next 50 years might hold and predicts that "long before our centenary year ... all positions now sacred to the male will have been taken over by women." He went on to make certain remarks in jest about

567-447: The validity of Maxwell's displacement current. This spawned an exchange of letters to the editor which lasted for years. The website contains a regular blog spot, whitepapers, webinars, a directory listing, guest forums, and events listings. All news is also updated on Twitter, LinkedIn, Facebook and Google+. Electronics industry The electronics industry is the economic sector that produces electronic devices . It emerged in

594-613: The winding of the high-voltage CRT deflector coils (not a task for the faint hearted). A similar series was published after 1945 utilising the then ubiquitous EF50 RF pentode amplifier valve (tube). With the outbreak of World War II and the expected shortages of paper and other resources, the publication reverted to being monthly, a frequency that it still retains to this day. The title was changed in September 1984 to Electronics and Wireless World , and from January 1996 (vol 102, no. 1718), to Electronics World . A sister publication

621-679: The world leaders in producing electronic waste, each tossing away about 3 million tons each year. China also remains a major e-waste dumping ground for developed countries. The UNEP estimate that the amount of e-waste being produced – including mobile phones and computers – could rise by as much as 500 percent over the next decade in some developing countries , such as India. Increasing environmental awareness has led to changes in electronics design to reduce or eliminate toxic materials and reduce energy consumption. The Restriction of Hazardous Substances Directive (RoHS) and Waste Electrical and Electronic Equipment Directive (WEEE) were released by

648-448: Was Wireless Engineer which was more of a learned journal than a popular magazine, featuring high quality, technical articles. In Wireless World ' s October 1945 issue, Arthur C. Clarke (then of The British Interplanetary Society ) published a now-famous article, "Extra Terrestrial Relays", which foresaw the coming of communications satellites in synchronous orbit around the Earth. Clarke pointed out that three satellites in

675-681: Was intended for teaching the basic principles of computer operation. In 1977 a series of articles was published based on the design of the NASCOM 1 computer. In 1979 they published a design by John Adams for a dual-processor desktop computer which included a novel high-level programming language. Entitled "A scientific computer", it was marketed as the PSI Comp 80 in kit form by the company Powertran . Contributors included M.G. Scroggie , who contributed articles of an educational nature on subjects such as applied mathematics and electronic theory using

702-502: Was superseded by The Wireless World. An Illustrated Monthly Magazine for all interested in Wireless Telegraphy and Telephony as its first issue was sold on news-stands. Publication of Wireless World continued uninterrupted throughout World War I, and from 4 April 1920 (vol. 8 no. 1) publication frequency was increased to fortnightly From 1 April 1922 it became known as The Wireless World and Radio Review following

729-422: Was used for early electronic devices, before later being largely supplanted by semiconductor components as the fundamental technology of the industry. The first working transistor , a point-contact transistor , was invented by John Bardeen and Walter Houser Brattain at Bell Laboratories in 1947, which led to significant research in the field of solid-state semiconductors during the 1950s. This led to
