  • Design for maintainability with particular reference to domestic radio and television receivers

    Publication Year: 1967, Page(s):195 - 198
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (533 KB)

    The main theme of this paper is that of designing good maintainability into a product from the viewpoints of (a) basic component reliability, (b) readily accessible test/monitoring points and (c) ready access and speedy changing of components or modules in cases of failure. The coming of colour television, with its greater complexity, emphasizes the need for attention to these points. View full abstract»

  • A review of methods of measuring system parameters in time-variant space communication channels

    Publication Year: 1967, Page(s):199 - 208
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1139 KB)

    The objective and methods of measurement on linear, timevariant communication channels are discussed with a view of assessing their applicability for the diagnostics of certain unconventional channels of interest to space communication. These may include channels formed during the early, powered phase of the space vehicle flight and during its re-entry into the Earth's atmosphere. No attempt is ma... View full abstract»

  • Handing over the design to the works

    Publication Year: 1967, Page(s):209 - 216
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1011 KB)

    In this paper the importance of effective communications is stressed. There are three stages in the handover: preparation, transfer and development. While there is still sufficient time to explore the reasons for disagreement between the parties each should be preparing the other to deal with problems which will be urgent later on. The formal transmission of design documents must take into account... View full abstract»

  • Some applications of computers in electronics design

    Publication Year: 1967, Page(s):217 - 223
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (884 KB)

    Design is seen as a complex activity requiring intellectual effort at several levels. The highest level is what we, rather loosely, call creative and corresponds with the selection (`invention¿) of potential schemes. There follows an analytical activity (`how does it work?¿) and finally a clerical operation (`how good is it?¿) which yields quantitative data on which the acceptability of the sch...

  • A multi-parameter data recording and processing system using magnetic tape

    Publication Year: 1967, Page(s):225 - 235
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1339 KB)

    This paper describes a flexible digital data recording and recovery system which will accept information of up to 76 bits per event at a rate variable from some 375 to some 48 × 103 bits per second (b/s), and replay at a rate of from 3 × 103 to 48 × 103 b/s. The total tape storage capacity is some 55 × 107 bits. The number of parameters recorded is limited only by the accuracy required and by ... View full abstract»

  • A rigorous theory of electromechanical delay lines

    Publication Year: 1967, Page(s):236 - 240
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (459 KB)

    Introduction of some insignificant restrictions into the theory of electromechanical delay lines gives rigorous solutions of great simplicity. These restrictions are: (a) the line shall be described by a two-row two-line matrix; (b) the transducers are represented by equivalent circuits with concentrated elements; (c) the transducers shall be electrically tuned to obtain the widest possible bandwi...

  • A silicon diode analogue multiplier

    Publication Year: 1967, Page(s):241 - 246
    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (608 KB)

    The logarithmic nature of the voltage-current characteristics of silicon junction diodes is exploited to design an analogue multiplier. Four silicon junction diodes are used in conjunction with a differential operational amplifier in the multiplier circuit. The principle of operation, design considerations and techniques to compensate for temperature effects and unequal diode parameters are discus... View full abstract»

  • Major causes of equipment unreliability

    Publication Year: 1967, Page(s):247 - 250
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (498 KB)

    Defect statistics on guided weapons and other equipment clearly indicate that the more unusual components and the `special to project¿ innovations show the highest failure rates. Electromechanical components are examples and such failures are emphasized in guided weapons as the total running time may be a few hours with only a few minutes in flight. This paper shows that since the design and shap... View full abstract»

  • Superdirective arrays: the use of decoupling between elements to ease design and increase bandwidth

    Publication Year: 1967, Page(s):251 - 256
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (772 KB)

    The design and achievement of superdirective receiving arrays for radio or acoustic waves can be greatly eased by the use of decoupling arrangements between the elements, such as buffer amplifiers in the output of each element before the outputs are combined to form the directional pattern. By this means, too, the severe bandwidth restrictions normally associated with superdirectivity can be remov... View full abstract»
