Active control of sound results from destructive interference between the sound field of an original acoustic source and that from a controllable array of 'secondary' acoustic sources. For this destructive interference to occur over an appreciable region of space the sound field of the secondary sources must match that from the primary source in both time and space. The spatial matching requiremen... View full abstract»
Telecommunications networks based on synchronous 64 kbit/s channels are too restrictive for the future realisation of integrated broadband networks. New switching and transmission techniques, particularly those based on asynchronous transfer modes (ATM), are required. Roke Manor Research Ltd. and Plessey Research Caswell Ltd. are actively developing these new techniques at a system and technology ... View full abstract»

Digital radio frequency memory (DRFM) is a technique in which high-speed sampling and digital memory is used to store radio frequency and microwave signals. It is becoming a popular technique for the implementation of false-target ECM systems. The author discusses the principles of DRFM and the advantages of alternative system architectures.<

A technique has been developed at Roke Manor Research Ltd. for recovering three-dimensional (3D) information from conventional video data. This is based on matching features in a scene observed from different viewpoints, either as a result of intrinsic camera or object motion or through the use of multiple cameras. The technique has been examined as a means of supplying guidance information to a r... 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.
