    Some recent papers on digital filter design have been concerned with the use of unconstrained minimization techniques, such as the Fletcher-Powell algorithm, to optimize the design to a prescribed frequency domain description. This paper looks, in detail, into the use of two variable substitution methods to bound the poles and zeros of the filter for stability and minimum phase considerations. One... View full abstract»

    The probability density and related properties of the relative error due to rounding after floating-point arithmetic operations can be computed from the distributions of the mantissa and its absolute error. Various results obtained, in particular, under different assumptions concerning the distribution of the mantissa are presented on a common basis and in such a way that they are independent of t...

    A detailed discussion of the computer simulation of a linear prediction vocoder system is presented. The basic technique used for analysis is the autocorrelation method of linear prediction. New results include modifications to the simplified inverse filter tracking (SIFT) algorithm for more efficient pitch extraction, coding algorithms for low-bit rate transmission, a simplified synthesizer gain ...

  • An algorithm for automatic formant extraction using linear prediction spectra

    An algorithm is presented which finds the frequency and amplitude of the first three formants during all vowel-like segments of continuous speech. It uses as input the peaks of the linear prediction spectra and a segmentation parameter to indicate energy and voicing. Ideally, the first three peaks are the first three formants. Frequently, however, two peaks merge, or spurious peaks appear, and the... View full abstract»

  • Parallel data streams and serial arithmetic for fast Fourier transform processors

    An algorithm is presented that introduces two degrees of parallelism into the implementation of fast Fourier transform (FFT) processors. That is, both the radix of factorization and the number of arithmetic units may be selected to achieve the required processing speed. A serial vector multiplier that is ideally suited to the implementation of a general radix arithmetic unit is described. It is su... View full abstract»

  • Variability and covariability of modified spectral estimators

    The use of data windows in digital spectral analysis causes a covariance between spectral components in the periodogram. The variability of the smoothed spectral estimator, obtained by a graded summation of adjacent periodogram values, is increased. These effects are analyzed for white Gaussian signals.

  • Fast Convolution using fermat number transforms with applications to digital filtering

    The structure of transforms having the convolution property is developed. A particular transform is proposed that is defined on a finite ring of integers with arithmetic carried out modulo Fermat numbers. This Fermat number transform (FNT) is ideally suited to digital computation, requiring on the order of N \log N additions, subtractions and bit shifts, but... View full abstract»

    A lumped parameter formulation for the electromechanics of a class of electret transducers is developed. An energy method is used to calculate the force of electrical origin and the technique is employed in the solution of two important electret transducer geometries. The results are checked by a surface integration of the Maxwell stress tensor. View full abstract»

    It is of importance to find the necessary and sufficient conditions under which the one-dimensional and two-dimensional processing of any general transform should be equivalent. These conditions are found. It is known that the Fourier transform does not possess the described property. It is shown in this paper that a one-dimensional Fourier transform cannot be equivalent to any two-dimensional tra... View full abstract»

    This paper discusses the use of linear programming techniques for the design of infinite impulse response (IIR) digital filters. In particular, it is shown that, in theory, a weighted equiripple approximation to an arbitrary magnitude function can be obtained in a predictable number of applications of the simplex algorithm of linear programming. When one implements the design algorithm, certain pr... View full abstract»

    The problem of designing recursive digital filters whose frequency response approximates an arbitrarily prescribed function in the Chebyshev sense on a single interval is considered. Certain degenerate cases where the best Chebyshev approximation is not equiripple are studied in detail, and an algorithm is given for determining the best Chebyshev as well as the best equiripple approximation. Final... View full abstract»
