Communication electronics
It is difficult to ignore the ubiquitous mobile phone that has brought about such remarkable changes in people′s daily lives, although when used carelessly in public places it is often associated with annoyance to others. Energized by people′s need to communicate with others whether for business or pleasure, the development of the mobile phone has been rapid and widespread, enabling us to keep in touch with others while on the move almost anywhere on the planet. Moreover, the demand for Internet access and for other services via the “mobile” is stimulating a wide range of facilities for this modern personal communication device that progressively gets “smarter”.

While we are using a mobile phone to make an international call, our message is being received by a communications satellite in orbit round the Earth. Countries that can afford to make the powerful rockets necessary to launch communications satellites are launching satellites for other nations. Europe has such a launch rocket, called Ariane. For example, in 2001 an Ariane rocket was launched from the European Space Agency launch centre in Kourou, French Guiana carrying a Direct TV-4S television satellite able to provide the Direct TV network in the US with 300 TV channels. Many of these communications satellites are being placed nowadays in what is termed a geostationary orbit. This is an orbit approximately 36 thousand kilometers above the Earth′s surface and taking 24 hours to orbit the Earth. Three such satellites, spaced at equal intervals of 120 degrees apart, provide coverage of the entire globe.

There is also GPS (Global Positioning Systems) technology which can find out, via satellite, exactly where you are. Some car rental companies are already using this technology to keep track of their vehicles. Mobile phone companies are even planning to use this technology in all their phones. This means that when someone makes a call on their mobile phone, or if they have their phone turned on, they can easily be located.

If astronomers are to keep in touch with an interplanetary spacecraft as it explores the Solar System, complex electronic receiving and transmission equipment is needed on board the spacecraft. A milestone was reached in a long distance interplanetary communication when the Voyager 2 spacecraft, launched from the Earth in 1977, was switched on by radio waves from the Earth to send back intriguing information about the outer planets Jupiter, Saturn, Uranus and it reached Neptune in 1989. This spacecraft is now in the remote regions of the Solar System and contact with it will continue for some time yet. However, communication with this highly successful spacecraft will be lost well before it reaches another star in about 350000 years! Unmanned spacecraft such as Voyager, Galileo, and Cassini accomplish feats of complex navigation that are hard to believe. But it is not just planets that are being explored, there has been a growing interest in examining comets.

In modern Earth-based telephone and data transmission systems, hair-thin glass fibers are being used instead of conventional wires. Enormous amounts of information are being carried down not by electricity, but by pulses of laser light, reflected repeatedly from the inside wall of the fibre. The combined use of optics and electronics in this way is called optoelectronics. When you make a phone call outside your local area you are almost certain to be using an optical fibre link with a laser sending the message down the fibre, and a detector receiving it at the other end. Optical fibre can carry far more information than copper wire and is the best way to link computers, outside broadcast TV cameras, banks, stock exchange dealing rooms, etc. There are other advantages, too. Strong magnetic fields from lightning and electrical machinery, do not interfere with the messages carried on the laser beam, and broken fibres are not a fire hazard since any laser light that escapes is unlikely to cause fire. Moreover, glass fibres are cheaper and lighter than copper wires so there are weight-saving advantages in, for example, aircraft and ships.

Evolution of stereo
In the late 1920s and early 1930s, researchers (begin) developing stereo. Around the early 1970s, some people like Ben Baur of CBS and Peter Scheiber, an independent consultant in Bloomington, Ind., (realize) that stereo was great, but everything (come) from in front of and between the two speakers. So quad, as it was called, was born, which used four speakers: left and right speakers in front of the listeners in conventional stereo and left and right speakers behind the listener to create the sensation of being “surrounded by sound”. While quad (develop), Dolby Labs (become) very successful with tape noise reduction systems. Its first systems (designed) for professional reel-to-reel units, but then Henry Kloss, founder of Advent Corp., (implement) a simplified version of the technology on a cassette deck, giving Dolby an entrée into the vast consumer market.

In the meantime, the film industry (struggle) with optical sound tracks, in use since the 1930s. The tracks (print) along the edge of the film, but were noisy, of poor quality, and degraded a little every time the film was shown.

Around 1977, when the original Star Wars movie (release), film producers wondered if they could not deliver something a little more exciting than the simple stereo. They (go) to Dolby, who (license) some of the original quad patents, and turned the speaker configuration into a diamond shape.

During the late 1970s through the early 1980s, the home video formats of the day, VHS and Beta, both (start) to support high-quality stereo sound track with VHS HiFi and Beta HiFi. The Dolby Stereo encoding of the original movie sound-tracks (transfer) to these tapes. Soon, most home audio-video receivers included Dolby Surround decoders significantly enhanced the perceived separation between the channels. Thus the average consumer could enjoy surround sound at home.
