    The author outlines the response of Seaward Electronic Ltd. to the European Directive on Electromagnetic Compatibility. The company looked at and rejected the test house option, internal test equipment and technical construction files. Instead Seaward Electronic started to address the knowledge and expertise problem. After consulting the country's leading EMC experts the company commissioned a suc... View full abstract»

    In safety-related systems, the issue of electromagnetic compatibility (EMC) is clearly even more important than in other installations. First, it is important that the equipment has sufficient immunity to avoid malfunctions due to electromagnetic interference, which might lead to danger either to people or property. Also, equipment which may not in itself have a safety role, should not interfere w... View full abstract»

  • Talking computers. Spanish work in speech processing

    Publication Year: 1994, Page(s):163 - 165
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (228 KB)

    Reliable speech recognition is one of the challenges of user-friendly computing. An Esprit project has brought speech processing in several languages much closer to commercial reality. The authors describe the Polyglot project in which the system for recognising isolated speech in Polyglot builds on a technology originally developed for Italian, extending it to cope with English, French, German, S...

  • Coded channels. Digital television by satellite

    Publication Year: 1994, Page(s):175 - 179

    Digital compression techniques will allow satellite TV broadcasting to continue to compete effectively with broadband cable. Instead of transmitting a continuously varying analogue electrical voltage to represent the picture, digital television converts each of the pixels that makes up a TV picture into a coded message. Provided that a receiver can decode the digital message, it can build up a com... View full abstract»

  • A navigator's guide to EMC

    Publication Year: 1994, Page(s):SUPL3 - SUPL8
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (360 KB)

    Surveys show that, although there is generally high awareness of the legal requirement to conform with the EMC Directive, confusion and uncertainty remain with regard to both the legal and technical issues. The EMC Directive will be fully implemented in all member states of the EU from 1 January 1996. It is imperative to recognise that after this date it will be a criminal offence to market electr...

  • EMC on the road

    Publication Year: 1994, Page(s):SUPL27 - SUPL28
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (140 KB)

    The European car industry is preparing its own product-specific directive, to take road vehicles out of the scope of the EMC Directive. The European automotive industry (ACEA, Association des Constructeurs Europeens d'Automobile) submitted a proposal to the European Commission that will exempt automotive electronics from the scope of the EMC Directive (89/336/EEC). This product-specific directive ... View full abstract»

  • Designing without numbers [computerised circuit design/analysis]

    Publication Year: 1994, Page(s):171 - 173
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (200 KB)

    The author describes how computers are taking even more of the drudgery of analysis out of circuit design. This is being achieved by the use of symbolic manipulation. The author describes an example using the Nodal and Mathematical tool to show how the technique of symbolic manipulation is used in circuit design View full abstract»

  • Travelling light. An all-optical transport network for telecommunications

    Publication Year: 1994, Page(s):159 - 162
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (280 KB)

    Conversions between optical and electronic signals is a major bottleneck in the physical layer of today's telecommunications networks. The author reports on a development that promises to take yet more electronics out of communications. The development is known as the Multi-Wavelength Transport Network (MWTN) project. The author describes the architecture of the MWTN optical node and in particular... View full abstract»

    Even without the Directive, EMC is a vital commercial and competitive issue; companies that use EMC effectively perform significantly better than those that do not. The author briefly discusses how to use EMC to the best effect View full abstract»

  • A quality look at quality management

    Publication Year: 1994
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (96 KB)

    The author briefly discusses the Science and Engineering Policy Studies Unit report on quality management. The new SEPSU report stands out from the mass of quality management literature in several ways. First, SEPSU is demonstrably not selling anything. Secondly, the report is based on data and driven by data. Thirdly, the report looks at quality management in the round, without disproportionate e... View full abstract»

  • The problem of size [EMC testing]

    Publication Year: 1994, Page(s):SUPL20 - SUPL22
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (196 KB)

    Some systems, such as telephone exchanges, are simply too large or too complex to undergo EMC testing in the normal way. Three main problems exist with the EMC Directive for large systems. First, the size of the open area test sites recommended in existing standards is often too small for large systems. Secondly, there is a requirement to vary the position of the cables attached to the equipment u... View full abstract»
