    The past decade has seen a revolution in television graphics. Here, the author examines the computer-based image processing equipment which has caused this revolution. He presents a short excursion into history which, he argues, is useful in understanding the way of thinking that produces such unsophisticated yet highly effective products View full abstract»

    Microwave engineering is characterised by its own distinctive design principles and manufacturing methods. The very high frequencies of microwaves present designers and manufacturers alike with problems not found in lower parts of the spectrum, giving microwave engineering a special nature of its own. The microwave spectrum is generally considered to begin at around 1 GHz. The upper limit is not so clearly defined: most applications are at frequencies below 26.5 GHz, but work is currently under way to develop systems working at up to 300 GHz in specialist areas. Established applications areas include satellite systems, line-of-sight communications, radar and electronic-warfare systems. The author aims to provide a taste of the special nature of microwave engineering by describing the design and fabrication processes of a modern high-resolution spectrum analyser, covering the microwave spectrum up to 30 GHz-the 2386 from Marconi Instruments View full abstract»

    Despite being a subject of controversy in Britain's educational establishment ever since it was first proposed some four years ago, the National Curriculum is now a reality. The purpose of this article is to describe it, and to discuss features that are especially important for the engineering profession, and particularly for electrical engineering View full abstract»
