    In this paper a design technique for the two-dimensional filters is proposed. An optimization algorithm is developed to minimize the p-error criterion under the constraint that the resulting filter be stable. Design of one-dimensional filter may be considered as a special case to which the proposed algorithm is applicable. Several examples are solved to illustrate the technique. View full abstract»

    This paper presents two formulations of multi-dimensional digital signals from one-dimensional digital signals so that multidimensional convolution will implement one-dimensional convolution of the original signals. This has reduced an important word length restriction when used with the Fermat number transform. The formulation is very general and includes block processing and sectioning as specia...

  • In situ narrow-band calibration of an acoustic receiver

    Publication Year: 1974 , Page(s): 56 - 62
    Request Permissions | Click to expandAbstract | PDF file iconPDF (496 KB)  

    A technique for in situ narrow-band calibration of an acoustic receiver is described. Wide-band Gaussian noise is applied through a random acoustic channel to the receiver and a reference. The resultant output spectra are estimated via Welch's method [1], and the unknown amplitude frequency response is estimated from the ratio of the two spectra. Statistical accuracies of the estimates are investi... View full abstract»

    This paper discusses the power spectral effects of spline interpolators. A general technique is given for finding the steady-state spectral effects of splines of all orders, when applied following uniform sampling of the input function. The following observations are made: 1) the even order splines that were examined (second and fourth order) possessed divergent steady-state frequency transfer fun... View full abstract»

  • Digital notch filter design procedure

    An analytical procedure for designing a linear digital notch filter is presented. The resultant filter is sixth-order and is implemented by cascading three second-order filters so as to avoid instability which may arise from computer coefficient truncation. The procedure outlined is straightforward, requires only simple algebraic steps, and gives filter parameter selection criteria for reducing th... View full abstract»

  • Monotonic passband low-pass filters with Chebyshev stopband attenuation

    A class of nonmaximally flat monotonic low-pass filters with sharp cutoff are discussed and shown to provide better magnitude response both in the passband and in the stopband than their maximally flat counterparts. The normalized pole and zero locations of these filters are tabulated for n = 3-11 and different values of the minimum stopband attenuation. View full abstract»

    Formal realization procedures for digital networks (simulation diagrams, state diagrams) are presented. The methods provide step-by-step realization of all network elements either by repeated divisions and order reductions, or a continued fraction expansion. A total of 14 basic canonical forms has been obtained. The determination of multiplier constants in all cases involves only simple divisions,... View full abstract»

  • Recursive digital filter synthesis in the time domain

    The nonlinear minimization problem that results from recursive digital filter design with phase constraints is simplified somewhat by working in the time domain. This paper describes techniques that utilize the time samples of the desired response as target values for an iterative minimization. Initial values for the α and β (feedforward and feedback) coefficients can be obtained by one ... View full abstract»

    In the absence of an anechoic chamber, far-field acoustic measurements free from coloration are difficult to obtain because of environmental reverberation and background noise. This paper describes an on-line digital processing system capable of optimizing the estimate of impulse response and frequency response under such conditions. Actual measurements demonstrate that properties of the transient... View full abstract»

    Iterative time domain design of recursive or nonrecursive digital filters requires the minimization of an error criterion E. If E is a differentiable functional, the most effective methods (like steepest descent, Newton's method, or conjugate gradient method) use first derivatives with respect to the parameters of the filter. Considering an arbitrary filter structure, it is shown in this paper tha... View full abstract»
