As part of the process of harmonisation of technical standards needed to achieve the single European market in 1992, the European Commission has proposed a directive on EMC. The author describes the requirements contained within the proposal and, since the proposal will refer to European standards for technical requirements, a brief outline of the standards-making procedure is included.<

Proposals for a European directive on electromagnetic compatibility are focusing attention on the techniques for measurement of noise and unwanted signal emissions from a wide variety of equipment. Assessment of the immunity of sensitive electronic equipment to electromagnetic disturbances, such as electrostatic discharges and RF transmissions, is equally important. The author includes an outline ... View full abstract»
An elementary reconsideration of first principles in aperture-domain processing of wave phenomena for reception (and, by reciprocity, for transmission) can yield revealing, and in some cases novel, insights into what can or cannot be achieved. The subjects covered here include direction-selective reception, superdirectivity, direction finding, focused near-field reception, circular arrays and circ... View full abstract»
Following the rapid growth of land mobile radio, increased attention is being paid to the provision of aircraft passenger telephony services. The author reviews the requirements for such services and outlines how modern technology will shortly enable worldwide aeronautical telephony to become a reality-via satellite. The current service provisions and enabling technologies are described and an ins... View full abstract»

Digitised colour images quantised at 24 bits per pel represent a considerable storage requirement. For many applications a coarser quantisation is allowable or even necessary. The authors describe three variations on a method to quantise RGB data at approximately 4 bits per pel. The main criterion in the scheme is that of a minimum perceptual distortion in the reproduced data. The MacAdam chromati... View full abstract»
Aims & Scope
Published from 1989-2002, the Electronics & Communication Engineering Journal aimed to inform practising professional engineers who were involved in electronics and communications by providing coverage of new developments in a serious technical, but not in an overformal or academic manner.
Topics covered included: Measurement and instrumentation; circuit design, simulation and CAD; signal and image processing, coding; microwaves, antennas and radio propagation; optoelectronics; TV and sound broadcasting; telecommunication networks; radio and satellite communications; radar, sonar and navigation systems; and electromagnetic compatibility.
