    When a fast Fourier transform (FFT) is implemented on a digital machine, quantization errors will arise due to finite word lengths in the digital system. The magnitudes and characteristics of these errors must be known if an FFT is to be designed with the minimum word lengths needed for acceptable performance. Two forms of FFT quantization, coefficient rounding and floating point arithmetic quanti... View full abstract»

    Linear prediction (LP) is presented as a spectral modeling technique in which the signal spectrum is modeled by an all-pole spectrum. The method allows for arbitrary spectral shaping in the frequency domain, and for modeling of continuous as well as discrete spectra (such as filter bank spectra). In addition, using the method of selective linear, prediction, all-pole modeling is applied to selecte... View full abstract»

    It is shown that for nonrecursive digital filters in the first canonic form the hardware requirements are proportional to the output rate. Using a low output rate, a relatively simple receiver for multifrequency-code (MFC) signals can be achieved. Linear phase bandpass pairs with a 90° phase difference are used to eliminate the input signal phase dependence. Narrow linear phase bandpass filte... View full abstract»

    This paper is based upon a presentation given at the 1974 Arden House Digital Signal Processing Workshop. The presentation discussed a method for designing two-dimensional recursive digital filters using a differential correction algorithm. A brief description of the algorithm and some design examples will be presented here. This design approach is compared to a similar approach used by Bednar and... View full abstract»

    The application of the coherence function between two wide-sense stationary random processes is considered, including methods for linear and nonlinear system analysis, measuring signal-to-noise ratio, and determining time delay. Examples of misleading results owing to improper model identification and biased estimation are presented. Estimation of coherence is studied with emphasis on how practica... View full abstract»

    An algorithm is proposed for extracting the pitch of voiced speech. The method is based on approximating a given segment of the speech waveform in a least-squares sense by a finite Fourier series. In the approximation the fundamental frequency of the Fourier series, as well as its coefficients, is considered variable. View full abstract»

    Several alternate sets of parameters that represent the linear predictor are investigated as transmission parameters for linear predictive speech compression systems. Although each of these sets provides equivalent information about the linear predictor, their properties under quantization are different. The results of a comparative study of the various parameter sets are reported. Specifically it... View full abstract»

    A normalized digital filter structure is presented, based upon an orthonormal polynomial expansion. This structure is recursively designed, has several predictable stability properties in the presence of time-varying parameters, and appears to have roundoff noise properties which are superior to other known filter structures, particularly in the presence of clustered poles. Each section of the fil... View full abstract»
