  • Analysis and synthesis of exponentially tapered, nonuniform transmission line impedance transformers

    Creator:
    David, Frank Kolar
    Abstract:
    The exponentially tapered, nonuniform transmission' line, applied as an impedance transformer, is analyzed and modified. The analysis develops an expression for the input reflection coefficient that has the magnitude and phase as distinct functions. This allows ease in comparing the approximate and exact solutions and in developing the S-parameters for...

  • Simplification of large linear systems using two-step iterative method

    Creator:
    Shoji, Fumihiro Frank
    Abstract:
    The order of the practical system (e.g. nuclear power plants, electrical power network and chemical plant) is quite large. However, there are many limitations in computing facilities for the large system. Because of these limitations, it is often necessary to reduce the order of the large system using an approximation....

  • Fuzzy logic control of an inverted pendulum with vision feedback

    Creator:
    Holzapfel, Frank G.
    Abstract:
    Recent technical progress has made new forms of controller implementations on computers possible. Especially the technique of Fuzzy Logic Control has found a growing number of applications. Also the development of fast A/D converters has made the acquisation of data with vision based systems possible. In this project we combine...

  • Design of CMOS switched-current filters

    Creator:
    Fiez, Theresa S.
    Abstract:
    The design and implementation of Switched-Current (SI) ladder filters is described. SI filters require only a standard digital CMOS process and the power supply voltage requirement is low. SI circuits also can be potentially operated at higher frequencies than Switched-Capacitor (SC) filters due to the low-impedance wideband nodes of the...

  • Duty-cycle controlled switched resistor techniques for continuously tunable, low-voltage circuits

    Creator:
    Kurahashi, Peter
    Abstract:
    A duty-cycle controlled switched resistor is a tunable resistive element that uses pulse width modulation as the method of tuning. This thesis will describe the operation of switched resistors and propose several circuit architectures that are well suited to the use of switched resistors. These architectures include filters, mixers, and...

  • A linear test bed for characterizing the performance of ocean wave energy converters

    Creator:
    Hogan, Peter M.
    Abstract:
    Determining the performance characteristics of various ocean wave energy converters (OWEC) has proven to be difficult due to problems replicating a baseline motion profile in the ocean or wave tank to compare these devices. The linear test bed seeks to mechanically simulate the relative linear motion between the active components...

  • The design of a single chip logic state analyzer

    Creator:
    Hung, Shih-chuan
    Abstract:
    This thesis describes the design of a single-chip logic analyzer. The utility of such a chip in measuring and recording digital system parameters is illustrated. Possibilities for future applications of this chip in performance monitoring of computer systems are discussed.

  • A comparative study of lowpass continuous-time delta-sigma modulators with pulse-shaped DACs

    Creator:
    Fang, Jie
    Abstract:
    Recently, continuous-time ΔΣ modulators are appearing increasingly often in both the literature and the marketplace due to their features of inherent antialiasing and relaxed requirements for opamp and so on. However, several nonideal factors such as clock jitter, excess loop delay, inter-symbol interference and so on, degrade the SNR performance...

  • RF and Millimeter-wave Techniques to Improve Scalability and Efficiency of Digital Beamforming Arrays

    Creator:
    Johnson, Manoj
    Abstract:
    Spectrum overcrowding, ever increasing demand for high data rate and increased mobility requirements are three major challenges 5G-technology is trying to address. In this thesis I start with a RF front-end technique that deals with blocker interference arising from spectrum overcrowding both across frequency bands and within the same frequency...

    Creator:
    Herr, Alan Jack
    Abstract:
    Most technological problems associated with man-machine conversations have been solved and are well documented in both the contemporary technical and lay literature. The major remaining technological problem is the real time conversion of a human's vocal uterances into a "written" phoneme sequence representing the information content of speech. The work...
