  • On piecewise-linear basis functions and piecewise-linear signal expansions

    A set of piecewise-linear (PL) basis functions for signal or functional decomposition is introduced. These basis functions provide a PL approximation to the signal and an a priori determination of the required number for a finite term expansion to achieve a certain pointwise approximation error. Moreover, the expansion coefficients are linear combinations of samples of the function to be expanded ... View full abstract»

    The implementation of the Linear Prediction Auto-correlation Vocoder (LPAV) with fixed-point truncation arithmetic is presented. For a speech bandwidth of up to 3.3 kHz, it is possible to implement LPAV with a maximum of 16-bit fixed-point arithmetic, thus allowing for very efficient software simulation on minicomputers or economical hardware implementation on a special purpose computer. The resul... View full abstract»

    Any digital filter can be decomposed into two basic subsets, an extrapolator the output of which is sampled at a frequency depending only on the filter bandwidth and an interpolator delivering the filtered signal at the imposed output sampling rate. Redundancy in extrapolator and interpolator is removed by introducing half-band nonrecursive filtering elements for which definition, performance figu... View full abstract»

  • Sequential least-squares Fourier estimation with fading memory

    Publication Year: 1974, Page(s):300 - 303
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (472 KB)

    Necessary and sufficient conditions are developed which insure finite fading memory least-square Fourier coefficient estimates from time and frequency domain data are equal. The implementation of such filters are also presented. View full abstract»

    This paper presents a random search computer design technique that is shown to be suitable to the solution of a class of waveform design problems. The class of problems considered is that class in which only the phase angles associated with a fixed power spectrum ensemble of sinusoids are varied so that the sum of the sinusoids approximates some desired waveform. Two illustrative peak-factor desig... View full abstract»

    The durations of initial and final consonant clusters in monosyllabic and bisyllabic words within a frame sentence were studied from spectrograms of readings by 3 speakers. The durations of consonants within a cluster varied with the features of the consonant and its phonetic environment, such as voicing and point and manner of articulation. A durational model was proposed based on two mechanisms.... View full abstract»

  • Unequal bandwidth spectral analysis using digital frequency warping

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (808 KB)

    The application to unequal bandwidth and vernier spectrum analysis of a technique referred to as digital frequency warping is discussed. In this technique a sequence is transformed in such a way that the Fourier transforms of the original and transformed sequences are related by a nonlinear transformation of the frequency axis. An equal bandwidth analysis carried out on the transformed sequence th... View full abstract»

    This paper presents a class of generalized continuous transforms for the orthogonal decomposition of signals. Base functions for the continuous transform range from Walsh functions of order two to stair-like functions which resemble approximations to sinusoids and which are distinct from the generalized Walsh functions. Standard desirable properties which are shown to hold for the generalized cont... View full abstract»

  • The thermo-acoustic properties of fibrous material

    Publication Year: 1974, Page(s):297 - 300
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (424 KB)

    The compressibility of air inside a loudspeaker enclosure can be increased if the enclosure can be made isothermal. Stuffing fibrous material into an enclosure tends to make it isothermal since the material acts as a heat sink. In order to evaluate the effectiveness of filling material in loudspeaker enclosures, the thermal time response of fibrous materials is calculated. The time response is fou... View full abstract»

  • On a signal detection problem and the Hadamard transform

    Publication Year: 1974, Page(s):296 - 297
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (304 KB)

    A signal detection scheme of moderate complexity is implemented using the Hadamard transform. The performance of the scheme is between those of a data editing system and a matched filter. The scheme is very simple to implement, requires much less computation than a matched filter and could be of considerable value when large amounts of input data are being processed.

  • A parallel arithmetic hardware structure for recursive digital filtering

    A flexible, low-cost hardware structure is described for implementing recursive digital filters. Either a parallel or cascade arrangement of any number of second-order filter sections may be implemented for each of the input channels. Although the internal arithmetic is fixed-point, filter coefficients may be represented in floating-point form to reduce coefficient roundoff error. View full abstract»
