    The paper describes the problems that are likely to be encountered when designing a voltmeter which uses the dual ramp technique. The compromises that are necessary especially with the switching of the reference and input signals are dealt with. The sources of all the major errors are investigated and the techniques that can be employed to reducethem are described. A method of adjusting the integr... View full abstract»

    Speech signals are produced by relatively slow articulatory movements. This suggests that the information rate of the speech signal is much less than would be expected by considering the bandwidth of the acoustic signal. Vocoders attempt to exploit the redundancy in the speech waveform by extracting and transmitting the information bearing parameters of the speech signal. At the receiver, these pa...

    Available techniques for the production of random numbers for digital computers rely on software which is relatively slow. Simple techniques for generating these numbers are available in hardware form which allows the full speed of the computer to be used to full advantage in simulation problems. Several possible practical arrangements are considered and their performances compared. View full abstract»

    The paper discusses the requirements for information processing system components, drawing attention to the parallel manner in which systems and components evolve. A short survey follows of optical techniques which may be applied to digital storage, and of systems wh ich have been produced in the past. Finally, suggestions are made as to optical storage systems which should have very desirable cha... View full abstract»

  • An oscilloscope polar coordinate display for multi-dimensional data

    Publication Year: 1970
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (522 KB)

    The paper describes in detail a simple electronic system which processes up to eight simultaneous analogue signals and displays them in the form of a polar coordinate diagram on a commercial oscilloscope with identical A" and Y amplifiers. Some preliminary subjective tests are briefly described, which confirm that the human observer can quickly detect several changes in the display and classify it... View full abstract»

  • Noise considerations in the design of current sources

    Publication Year: 1970, Page(s):102 - 104
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (312 KB)

    The inclusion of a current source in the input stage of an amplifier may seriously degrade the overall noise figure. Some commonly used input circuits incorporating bipolar transistors and j.f.e.t.s. are analysed, and simple criteria are developed for low-noise design of the current source. View full abstract»
