    CAMAC is a definite style for implementing the interface conditions which exidt when many channels of input/output information share a common data-processor/controller. The features of CAMAC are described to indicate the applicability of CAMAC-compatible equipment and programming to real-time situations. Some of these are illustrated by typical systems which use either a computer or a simpler device as the central processor/controller. View full abstract»

    A coherent sampling technique is described by which the v.s.w.r. of a pulse-biased semiconductor device mounted in a transmissio line may be measured with a sensitivity comparable to that obtainable in c.w. measurements. View full abstract»

    The paper reviews the theory by which amplitude and phase modulated (a.m.ph.m.) pulse trains can be represented by complex number sequences and the means by which they can be generated and processed. The synthesis of pulse trains to have a desired autocorrelation function is described, some useful short Huffman sequences derived from Barker sequences are presented. Finally, the z-transform is applied to the study of combination codes formed by combining shorter sequences. View full abstract»

    This paper considers the effect of full-wave logarithmic transformation of signals with known probability density functions (p.d.f.s). A general result for the output variance is derived and specific results given for the mean and variance values of several common p.d.f.s. The output autocorrelation function for the Gaussian case is also derived. View full abstract»

  • High-speed measurement of insulation resistance of capacitors and capacitive circuits

    Publication Year: 1971 , Page(s): 557 - 562

    A new method is described for high-speed measurement of insulation resistance of capacitive components compatible with present day requirements for 100% insulation test of capacitors. It is suggested that such an instrument opens the way to a new approach to insulation resistance measurement which may lead to a revision of long established test specifications. View full abstract»

  • A cellular array which represents the inertial motions of objects

    Publication Year: 1971 , Page(s): 563 - 568

    Arrays of identical, uniformly connected circuits are described, which can represent the inertial motions of a group of objects. The objects are represented by `object words¿, which are propagated within a planar array. Applications for traffic control systems, image-processing and artificial intelligence are proposed.

    This paper adds the concept of interelement mutual coupling to a previously presented design technique for aerial arrays. With mutual coupling accounted for, one can realistically design electronically scanned arrays of wire elements that have both maximum gain and a number of independent, steerable nulls in the radiation pattern.
