A quiet revolution is taking place in communications technology, where light is replacing its low-frequency counterparts, the radio wave and signals by wire. The author traces the development of optical communication technology from simple beginnings using fire and beacons, through early valve and solid-state devices to integrated optics and advanced fibre systems. Because of the very rapid growth... View full abstract»

Chaos, apparently disordered behaviour which is nonetheless deterministic, is a universal phenomenon which occurs in many systems in all areas of science. For it to take place, the equations describing the situation must be nonlinear and, therefore, they are rarely solvable in closed form. Since the advent of fast digital computers, the theory of nonlinear systems has become much more accessible t... View full abstract»
The conventional circuit theory of uniform two-conductor transmission lines (TEM mode) assumes that at any cross-section the current in one conductor is equal and opposite to that in the other. This is not necessarily true, and even when it is true the resulting theory does not permit solution of some simple problems such as evaluation of the voltage difference between two points on the same condu...

The principles underlying optical detection are reviewed and the practical realisation of devices and receivers for digital optical communications is discussed. Some emphasis is placed on the advanced receiver signal processing techniques-both electronic and optoelectronic-that are now coming forward to provide a performance approaching the fundamental limits imposed by quantum mechanical consider...

The results of new subjective tests on the visibility of noise in System I PAL colour television are reported. Three forms of noise are considered: white (flat) noise, de-emphasised triangular noise, and the noise resulting from vestigial sideband demodulation (VSB noise). The results are compared with those given by work published 20 years ago and it is concluded that observers today are more cri... 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.
