    An X-band radar with back-to-back horizontally and vertically polarized antennas of equal gain and beamwidths was built. The antennas were enclosed in a symmetrical aerodynamic radome permitting speeds of rotation from 20 rev/min to 600 rev/min. The radar power was switched every half revolution from one antenna to the other, so that a sea-clutter picture presented on the top 180° of the p.p.i. d... View full abstract»

    Workers in the field of colour television broadcasting may find some of the contents of this paper interesting or provocative. The working party has been very conscious all along that many of the figures quoted were open to question either because of lack of solid information or because of differences in techniques and practices, and would therefore welcome comment and contribution. Comments shoul... View full abstract»

  • Waveguide solutions by the finite-element method

    A finite-element method based on a function minimization techinique is developed for analyzing homogeneous waveguide problems. The continuous eigen-value operator as in the Ritz finite-difference method is replaced by a matrix operator. The resulting equations are, however, matrix eigen-value equations. Relevant properties of the matrices are discussed. It is demonstrated that the method has advan... View full abstract»

    If the fundamental consideration of domain size were the dominant factor, it would theoretically be possible to store information on magnetic disks with a packing density of at least 1010 bits per square inch. To be of practical use, the fundamental design limits of the data channel and its components, the practical magnetic design of the media and recording heads, the mechanical tolerances and we...

  • Optimum transfer functions for feedback control systems with plant input saturation

    Publication Year: 1969, Page(s):233 - 247
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1472 KB)

    A method for the determination of optimum transfer functions for systems controlling plant with input saturation is presented. The procedure is demonstrated on a specific plant well studied in the literature, and the general conclusions verified by simulator and digital computer results. It is established that the desired system bandwidth should be obtained with a dominant system transfer function... View full abstract»
