    A fast sequency ordered Walsh Transform algorithm is presented, which is the complement to one developed by Manz. It is in place, is its own inverse, and accepts data in normal order, returning the coefficients in bit-reversed sequency order. View full abstract»

    Recent experiments in speech synthesis have shown that, by an appropriate eigenvector analysis, a set of orthogonal parameters can be obtained that is essentially independent of all linguistic information across an analyzed utterance, but highly indicative of the identity of the speaker. The orthogonal parameters are formed by a linear transformation of the linear prediction parameters, and can ac... View full abstract»

    A maximum likelihood (ML) estimator is developed for determining time delay between signals received at two spatially separated sensors in the presence of uncorrelated noise. This ML estimator can be realized as a pair of receiver prefilters followed by a cross correlator. The time argument at which the correlator achieves a maximum is the delay estimate. The ML estimator is compared with several ... View full abstract»

  • An improved algorithm for ordering poles and zeros of fixed-point recursive digital filter

    An improved algorithm is presented for ordering the poles and zeros of fixed-point recursive digital filters so as to minimize the effect of roundoff noise. The method proceeds by successive improvement, and yields local optima which cannot be improved further by interchanging a pair of poles or zeros. The resulting assignments found for four filters of orders 8-22 are the best known. View full abstract»

    Expressions for the coefficient sensitivities of cascaded digital lattices introduced by Itakura and Saito and further developed by Gray and Markel are calculated using chain parameters. It is shown that a cascade of lattices with ε = +1 exhibits zero coefficient sensitivities at zero frequency. View full abstract»

    Two commonly used signal analysis techniques are linear prediction and homomorphic filtering. Each has particular advantages and limitations. This paper considers several ways of combining these methods to capitalize on the advantages of both. The resulting techniques, referred to collectively as homomorphic prediction, are potentially useful for pole-zero modeling and inverse filtering of mixed p... View full abstract»

  • An ADPCM realization of nonrecursive digital filters

    A realization of nonrecursive digital filters using adaptive differential pulse-code modulation (ADPCM) as the analog-to-digital conversion scheme is presented. Output samples are computed by a sequence of read-only memory (ROM) lookups, shifts, and additions, thereby eliminating multipliers from the filter structure. Such ADPCM filters can typically operate three times faster than comparable PCM ... View full abstract»

  • Further considerations in the design of decimators and interpolators

    In this paper several issues concerning the design and implementation of multistage decimators, interpolators, and narrow-band filters are discussed. In particular, the question of designing these systems in terms of minimum storage rather than minimum computation rate is examined. It is shown that a design which uses finite impulse response (FIR) filters for each stage, and which is minimized for... View full abstract»

    Time-domain methods for the design of recursive digital filters using a squared error criterion are compared with a frequency-domain technique. Levy's method, which has been used to estimate transfer functions of continuous-time systems is modified to obtain design equations for digital filters. A special case of Levy's method is shown to be essentially equivalent to the time-domain methods. View full abstract»

    Number theoretic transforms (NTT's) that can be used for the convolution of complex integer sequences are defined. A unified setting is provided wherein these transforms may be defined for all odd moduli, thus extending recent results on this topic. Multiplication-free implementation of certain of these transforms is possible. When these transforms are used to implement convolution, the resulting ... View full abstract»

    An important consideration in speech processing involves classification of speech spectra. Several methods for performing this classification are discussed. A number of these were selected for comparative evaluation. Two measures of performance-accuracy and stability-were derived through the use of an automatic performance evaluation system. Over 3000 hand-labeled spectra were used. Of those evalu... View full abstract»

  • The enhancement of speech intelligibility in high noise levels by high-pass filtering followed by rapid amplitude compression

    This paper presents the results of an examination of rapid amplitude compression following high-pass filtering as a method for processing speech, prior to reception by the listener, as a means of enhancing the intelligibility of speech in high noise levels. Arguments supporting this particular signal processing method are based on the results of previous perceptual studies of speech in noise. In t... View full abstract»

  • An error analysis for a vector model of two-dimensional recursive filter

    The problem of bounding the output quantization errors in linear two-dimensional recursive filters is examined. A two-dimensional filter is analyzed by developing a model for the filter based on a vector formed from the two-dimensional output sequence. A deterministic bound is obtained and then applied to a special class of second-order filters. View full abstract»
