Noise pollution is classified as the second most important cause of causing health ailments around the world and is right behind air pollution. Research shows that about 40 million adults in the U.S. alone have hearing damage in one or both ears that may be due to noise exposure.Approximately 22 million adults in Europe are directly affected by noise pollution that comes from traffic, industry, aircraft, or railways.
- an overview of radio and wireless technology and some of the major radio adn wireless applications.Radio is very widely used in everyday life now, and it is becoming more widely used as new applications are being found all the time. One of the original terms for radio was wireless, end even today many people refer to a radio as a wireless set.
While changing the amplitude of a radio signal is the most obvious method to modulate it, it is by no means the only way. It is also possible to change the frequency of a signal to give frequency modulation or FM. Frequency modulation is widely used on frequencies above 30 MHz, and it is particularly well known for its use for VHF FM broadcasting.

It is many years now since the name Hertz was adopted as the unit of frequency.It is fitting that this was done for a brilliant man as Heinrich Hertz, who gave so much to furthering science but died so young.It was Heinrich Hertz who laid many of the foundations of our modern radio technology and enabled it to be what it is today.
Radio Coherer History Includes:Summary of iconic radio receiversRacal RA17Almost countless radio receivers have been designed, but some have become more famous or represent major improvements in radio receiver design performance.On this page we will aim to list some that, in our opinion, have become a major milestone in receiver design, or they are of interest to many.

Spark Gap Transmitter History Includes:Spark gap transmitter historyOperationPoulsen arc transmitterSpark gap transmitters were the first type of radio transmitter to be widely used.As the name indicates the transmitters used a spark generated across a spark gap in the transmitter.Spark transmitters were particularly widely used on board ships where they provided the first means of communication to shore based stations.
Codes & abbreviations includes:SummaryAbbreviationsRST codeQ codePhonetic alphabetOften called the radio phonetic alphabet, this alphabet is widely used for two way radio communications, and other telecommunications services to convey letters unambiguously where interference and bandwidth limitations often make it difficult to distinguish accurately between different letters.
- the history of the development of the integrated circuit - how it was developed, the main names of Noyce, Kilby, Project Tinkertoy, etc.The history of the integrated circuit is one of the most important stories within the electronics arena.The history of the integrated circuit shows that the IC developed as a result of the need for very small electronic assemblies.
Sir Edward Victor Appleton was one of the key figures of the twentieth century who contributed to the knowledge of radio and the ionosphere and hence improved our knowledge of the way in which radio waves propagate in the HF portion of the spectrum.Edward Appleton received a Nobel prize in 1947 for his work, the technique for which laid the foundations for the development of radar.
It has been said that Thomas Edison is more responsible than anyone else for creating the modern world as we know it today. With inventions such as the phonograph, the electric light bulb, and 1093 patents to his name this is possible quite true. But surprisingly for such a great genius he was slow to learn as a child, not even talking until he was four years old.
The company was established over 35 years ago by husband and wife team Keith and Linda Hewitt. From humble beginnings trading from a small unit in St Helens with initially just one franchise agreement, the business has grown to become a celebrated and successful company which represents over ten of the industry’s top connector manufacturers.
Working From Home Includes:How to work from homeWorking from home is becoming increasingly common. There are many advantages to it, and employers are growing accustomed to it.Working from home can also be an ideal solution when setting up a business as it is often cheap, convenient and easy.However there are some dangers, and so to make working from home as successful as possible, enjoying the benefits rather than the disadvantages, it is best to set in place some ground rules.
The origins of Thurlby Thandar instruments Ltd date from the late 1970s when two separate companies, Thurlby Electronics Ltd. and Thandar Electronics Ltd. were both designing and manufacturing electronic test equipment within close proximity at St. Ives in Cambridgeshire, England.Through the 1980s, Thurlby specialized in bench power supplies, high resolution multimeters and digital storage units; whilst Thandar specialized in function generators, frequency counters and logic analysers.
Yokogawa has been developing measurement solutions for 100 years, consistently finding new ways to give R&D teams the tools they need to gain the best insights from their measurement strategies. The company has pioneered accurate power measurement throughout its history, and is the market leader in digital power analysers.
Pico Technology Test & Measurement products are used by scientists, technicians, engineers and researchers to troubleshoot their designs and validate performance of their systems with precision and within budget.PicoScopes capture and display complex waveforms that are the heartbeat of next generation electrical and electronic technologies.
Intel was founded in California, in 1968 by Gordon E. Moore - the inventor of Moore’s Law, and Robert Noyce, a physicist and co-inventor of the integrated circuit.The name is based on the words Integrated electronics, although the word now has connotations about the word Intelligence and this too is quite apt.
As the name indicates the business at Maury Microwave is focussed on microwave electronics, but ore specifically on the measurement and calibration aspects that can prove to be so difficult to achieve successfully.Maury Microwave is a supplier for microwave electronics orientated calibration, measurement and modelling solutions.
