    In algebra, the values of a polynomial over a wide span of time can be inferred from its value and that of its derivatives, measured over a very short span of time. Somewhat analogously, closely-spaced measurements, defining the fine structure of the phase and amplitude distribution over a narrow antenna aperture, can provide the information conventionally obtained from a similar number of element...

  • A high-frequency-optimized RC-active filter based on the Wien bridge

    The sensitivities to amplifier gain-bandwidth product of two active filters based on the Wien bridge are compared. It is shown that the performance of one of the filters can be optimized to give significantly smaller shifts in resonance frequency and Q-factor than the other filter which is generally recognized as the `standard¿ circuit.

  • Coefficient plane models for tracking system design

    Publication Year: 1975, Page(s):465 - 471

    A traditional method of designing the `fine control¿ mode of tracking systems is via the Bode plot relating system output to system error. This approach has a major disadvantage in failing to yield estimates of the system dynamic performance other than on an empirical basis which is somewhat unreliable. The paper shows how coefficient plane models may be used to solve this problem. Radar tracker ... View full abstract»

  • The finite element method for potential calculations in a Hall plate

    Publication Year: 1975, Page(s):472 - 474
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (289 KB)

    The potential equation in a Hall plate is solved by an expansion method. The first-order expansion can be replaced by a variational principle which enables the finite element method to be used. This technique can be applied to arbitrary geometries and numerical results are presented for a rectangular Hall plate. View full abstract»

    The paper deals with the design and construction of a dynamic data storage cell using stripline techniques, the data bit rate being 1 GHz. Taking into account both ohmic and dielectric loss factors, stripline losses have been computed and calculations indicate that, within the structure described, data bit rates up to 2 GHz are feasible.

  • A two-step strategy for character recognition using geometrical moments

    This paper discusses the use of geometrical moments as possible information-extracting features for recognizing characters. The development of decision criteria is traced from the normal multivariate probability function to the Hamming distance, and the relative efficiencies compared. Decision boundaries are investigated by a stepwise transformation from character to character. Computer simulation... View full abstract»
