    The transmitter power requirements for adequate field strength are evaluated for direct broadcasting in the present u.h.f. television bands. It is shown that improved aerials, the use of preamplifiers and wideband frequency modulation will be necessary for practical transmitters in existing or foreseeable space vehicles. The concept of `indicial bandwidth¿ is introduced which is defined as the re... View full abstract»

    The particular effects of noise upon logic gate and flip-flop circuits and the resultant general effects upon digital systems are considered. Common sources of noise are outlined andtheir significance in integrated circuit systems is considered. Such sources include crosstalk, reflections, common-earth impedance coupling and supply line noise. Present methods of assessment and specification of d.c... View full abstract»

  • Ruthenium resistor glazes for thick film circuits

    Publication Year: 1968, Page(s):299 - 304
    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (723 KB)

    The rapid development of thick film micro-circuits has created a need for preparations that will provide resistor films on a variety of substrates. Until recently the majority of theresistive preparations available required a firing profile with a peak temperature around 750°C, necessary to complete complex chemical changes within the glaze resistor. This not only imposed the need for very close ... View full abstract»

  • An R-C synthesis procedure for nth-order rational transfer functions with maximum gain constant and low number of components

    Publication Year: 1968, Page(s):305 - 310
    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (627 KB)

    A passive R-C synthesis for nth order rational transfer functions is presented. The synthesis is very simple in application and the networks realized are of the parallel ladder type. The main features of this procedure are maximum gain, minimum number of components, and reasonable component value spreads. View full abstract»

  • High-frequency mixers using square-law diodes

    Publication Year: 1968, Page(s):311 - 316
    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (505 KB)

    The use of symmetrical and asymmetrical space charge limited (s.c.l.) square-law diodes as mixer elements is considered, and it is shown that low conversion loss is possible with the latter type. In order to achieve this a d.c. bias is necessary on the diode. Matching source and load resistances are higher than for the unbiased diode. The use of an idler termination at the sum frequency (p+q) is s... View full abstract»

  • A satellite-borne receiver for low-frequency radio astronomy

    Publication Year: 1968, Page(s):317 - 323
    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (1421 KB)

    A receiver designed to measure the galactic noise spectrum in the range from 2 to 4.5 MHz and flown in the Ariel III satellite is described. Problems arising from the use of a loop antenna with a swept receiver and the exclusion of spurious signals from terrestrial sources and other experiments in the payload are discussed. Preliminary results indicate a marked coupling between the receiver and an... View full abstract»

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.
