    Conventional magnetic heads are not suitable when a large number of narrow tracks have to be recorded simultaneously. Attention has therefore been directed to types of head in which the magnetic field is produced by a relatively large current in short sections of a small diameter wire, without using any magnetic circuit. In this way it has been possible to record 40 tracks simultaneously on ¿ in ... View full abstract»

  • The scalar and vector potentials of the infinite sheath helical aerial

    Publication Year: 1964, Page(s):21 - 25
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (416 KB)

    From consideration of the surface charge density and the linear current density on an infinitely long sheath helix, expressions are derived for the scalar and vector potentials, from which in turn the field quantities are evaluated. By considering one further boundary condition the characteristic equation for the helix is derived. View full abstract»

  • Modes of oscillation of a grounded grid cyclotron oscillator

    Publication Year: 1964, Page(s):27 - 36
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (972 KB)

    A linear analysis of a grounded-grid cyclotron oscillator considering the effect of all the important circuit elements is presented. It is shown that the oscillator may execute oscillations at one of the cyclotron-dee resonant frequencies and/or at one of the coupling transmission line frequencies. The conditions of excitation of these oscillations are derived. Experimental evidence obtained from ... View full abstract»

  • Design of transistor I.F. amplifiers-stability and power gain

    Publication Year: 1964, Page(s):37 - 54
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1624 KB)

    The two most important stability criteria are presented and expressions for power gain are given in terms of them. Expressions for the input admittance of a stage are given, and the beneficial effects of loading the input port are shown. The interaction of stages is discussed with reference to overall stability. The advantages and disadvantages of making all stages of a multistage amplifier identi... View full abstract»

  • A high-efficiency low-frequency power source for vibration excitation

    Publication Year: 1964, Page(s):55 - 63
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1081 KB)

    The production of continuous sinusoidal vibrations of low frequency or transients of a comparably long period is beyond the scope of existing electro-dynamic force generators in which displacement is relatively limited. Moreover, the transformer-coupled amplifiers employed to drive the units have a limited low-frequency bandwidth unable to cater for the pulse shapes required. This paper describes ...

  • Design principles of the magnetic tape system for the atlas computer

    Publication Year: 1964, Page(s):65 - 73
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1009 KB)

    Atlas is a high speed computer typically performing a floating point addition in 1.4 ¿s. It has been designed to accommodate information transfers from eight tape channels simultaneously, information either passing into or out of the computer. Under these circumstances the computer has to deal with a transfer rate of 7.2 × 105 6-bit characters per second. A switching system interconnecting tape ... View full abstract»

    The paper describes various aspects of radar processing techniques which are being studied in order to determine their effect on overall system performance. Many data extraction systems make decisions regarding the presence or absence of targets by comparing the amplitude of the envelope of the demodulator output with a threshold which depends usually on the prevailing noise level. Studies have be... View full abstract»
