  • Tone burst deconvolution

    Creator:
    Rathja, Roy C.
    Abstract:
    The suitability of discrete least-squares optimal (Wiener) filters for deconvolution of tone-burst waveforms is studied. It is shown that: (1) such waveforms are not well suited to these filters without preprocessing, (2) the use of exponential weighting results in a significant improvement in filter performance and (3) that "phase-unwrapping" in...

  • Analysis and modeling of electrically long MESFETS and coupled schottky lines

    Creator:
    Mohammed, Ahmed Sarhan
    Abstract:
    The properties of linear active coupled lines consisting of electrically long GaAs MESFET structures are investigated for possible applications as traveling-wave broad-band amplifiers. In addition, the nonlinear coupled Schottky lines are studied for applications as voltage tunable circuit elements. The analysis of the general active asymmetric coupled transmission lines in...

  • Ocean electrical energy generation : An overview and potential for Oregon's Territorial Sea

    Creator:
    Smith, Gary Frederick
    Abstract:
    This report deals with the current status of four promising sources of electrical energy generation from the oceans. They are, in sequence; Ocean Thermal Energy Conversion: Where energy is obtained by exploiting the temperature differences between warm surface waters, and much deeper colder waters. Tidal Energy: Where differences in water...
