    The examination of a suspect transistor to determine its mode of degradation or failure always includes, at an early stage, checks on its junction and transistor characteristics, usually with the aid of a visual display on a curve tracer. This paper discusses the diagnostic significance of some of the abnormalities which may be observed on such displays. View full abstract»

    Optimum performance of a control system in terms of its time domain response can be achieved by the use of a bang-bang controller. The binary nature of the control signal together with the inherent complexity of a controller designed to achieve optimum bang-bang control high-order systems, immediately suggests the use of an on-line digital computer. Previous methods of attempting bang-bang control... View full abstract»

    It is shown that networks can be produced to correct accurately the effects of the non-linear transfer characteristics of a cathode-ray tube. The gamma correction required is related to the undesirable non-linearity in mathematical terms and the basic gamma equation evolved. A simple exponential equation can be converted into a gamma equation by the introduction of a linear function and the approp... View full abstract»

    After outlining some of the problems associated with the design of fluid flow networks a brief survey is made of the methods whereby such systems have been simulated. The use of analogue techniques for this purpose is discussed and an attempt has been made to compare the various methods proposed. As a result of this study certain improvements were considered to be worth seeking, and a new type of ... View full abstract»

  • Methods of increasing global communications capacity by adaptive selection of channels

    Publication Year: 1969, Page(s):305 - 311
    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (1084 KB)

    This paper is concerned with the selection of optimum channels for communication through media of which the quality is varying from any cause, including changing levels of interference. In particular it demonstrates the advantage of adaptive frequency selection when a block of channels is shared by relatively large numbers of random intermittent users, as is now the case with many portions of the ...

Aims & Scope

Published from 1963 to February 1964 by the British Institution of Radio Engineers and from March 1964 to 1984 by the the Institution of Electronic and Radio Engineers, The Radio and Electronic Engineer published papers describing original research and development in all branches of electronic engineering, as well as critical and interpretive surveys. Short contributions dealing with device technology, circuit techniques and experimental methods were also included.
