  • Frequency domain deconvolution

    Creator:
    Tan, Hin Leong
    Abstract:
    Frequency domain design of deconvolution filters is studied using Fast Fourier Transform. Filters for both the spike and the Gaussian reflector wavelet are obtained. True deconvolution filters are infinitely long IIR filters, and frequency domain analysis is an effective way of finding its optimum finite length approximation for an arbitary...

  • Variable linear phase digital filters

    Creator:
    Acuna, Fernando R.
    Abstract:
    Linear phase variable filters that are obtained with a frequency transformation of the form cos(ω) = P(cos(W)) were analyzed, where P is a finite degree polynomial, ω is the prototype frequency and W is the transformed filter frequency. A new transformation of third order is proposed. The new variable filter...

  • ISPS in system design

    Creator:
    Sakallah, Faten A.
    Abstract:
    This dissertation demonstrates the utility of the Instruction Set Processor Specification (ISPS) in a design environment. Although ISPS supports a wide range of applications in the areas of architecture evaluation and certification, design automation, software generation and fault simulation, the .emphasis in this dissertation is focused on using it in...

  • Speech deconvolution using Gaussian pulses

    Creator:
    Asadi, Mohammad Ayman O.
    Abstract:
    This dissertation introduces a new idea for frequency domain deconvolution of speech signals. The idea is to approximate a unit sample by a Gaussian pulse. The deconvolution is performed by designing a glottal inverse filter that will estimate the excitation of the vocal tract. Then, the excitation will be used...

  • A survey of optimal frequency domain deconvolution methods

    Creator:
    Gamage, Gayani N. K.
    Abstract:
    The resolution of multiple overlapped reflections is achieved by designing inverse filters using frequency domain deconvolution. A careful study reveals a number of problems involving frequency domain design of spike inverse filters. These include the presence of noise and aliasing in both the filter response and its output resulting from...

  • A multi-microprocessor debug executive

    Creator:
    Edmonds, Douglas E.
    Abstract:
    The system in this thesis uses multiple Intel iSBC86/12A cards connected to the Intel Multibus. The system was written using the Intel language PLM86. The final result is a low level debug tool that provides the user with the following capabilities: examine/change memory, examine/change processor registers, load a user written...

  • Implementation of an Ethernet Local Area Network board for the MacIntosh II system

    Creator:
    Yoo, Tae-On
    Abstract:
    The purpose of this study was to design and to implement a practical Ethernet Local Area Network (LAN) board for the Macintosh II computer system. A survey of the literature provided a general definition of LANs, a reference model for network layers, specifications for an Ethernet LAN, and information on...

  • Cursive script recognition using a dynamic time warping method

    Creator:
    Koehler, Loren M.
    Abstract:
    This thesis is concerned with the problem of achieving accurate recognition rates for Cursive Script Recognition (CSR). Cursive Script Recognition is difficult due to writer variations such as script formation and time non-linearities. This research entailed analysis and implementation of a Cursive Script word-level Recognition system using Dynamic Time Warping...

  • A graphical ethernet monitoring system (GEMS)

    Creator:
    Park, Chung Min
    Abstract:
    GEMS (Graphical Ethernet Monitoring System) is an enhancement to the SU-PC/IP NETWATCH program, for the graphical display and recording of computer network packets. SU-PC/IP (Stanford University Personal Computer/Internet Protocol) NETWATCH displays one line of information per packet, including the packet type, IP addresses, packet size, and protocol type, etc. This...

  • An efficient data transfer protocol for Ethernet

    Creator:
    Hegde, Anoop R.
    Abstract:
    Most general purpose protocols are found to suffer from inefficiency in an Ethernet LAN environment when used for large volume data transfer. This is especially true with the TCP/IP family which was designed for a wide area network. This research work presents a proof of this inefficiency and proposes a...
