  • Pattern recognition of speech using hybrid computer feature extraction

    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...

  • Computer analysis of a class of acoustic signals

    Creator:
    Miller, Michael Robert
    Abstract:
    A procedure for displaying cursory computer analyses of time series acoustic signals is described. The graphic presentation is optimized for visual analysis. The results displayed represent time series signals and/or Power Spectral Density estimates. Both hardware and software components of the procedure are described and compared with current methods. Suggestions...

  • A study of time series interpolation and decimation with signal processing applications

    Creator:
    Kraemer, Thomas Fredrick
    Abstract:
    Decimation and interpolation is shown to be an effective technique for reducing the storage requirements for bandlimited time series. Interpolation and decimation is theoretically developed using z-transform theory and graphically interperted. A sequence of data acquired by sampling a sonar signal is used to demonstrate the effects of decimation. Using...

  • 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...

  • 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...

  • A microprogramming learning system

    Creator:
    Mammen, M. Ninan
    Abstract:
    A microprogramming teaching tool was designed and implemented. This tool was based on the Am 2900 bitslice microprocessor family. It provides tools for understanding software development for a simple bitslice microprocessor.

  • Team differential games and non-linear signal processing

    Creator:
    Bugnon, Francois J.
    Abstract:
    Team pursuit-evasion games are studied here with one performance index for the team as a unit in competition with one common opponent. Particular structures of team games are discussed after a brief introduction of the two-player differential games. The classical calculus of variations is used to derive the feedback strategies...

  • 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...
