    Some explicit frequency domain ∞-norm error bounds for 2-D model reduction of denominator separable systems are derived. They are based on 1-D balanced model reduction and Hankel approximation methods. The evaluation of these error bounds only involves the computation of Hankel singular values of two 1-D transfer matrices View full abstract»

    A class of hardware algorithms for implementing the Lempel-Ziv-based data compression technique is described. The Lempel-Ziv-based compression method is a powerful technique for lossless data compression that gives high compression efficiency for text as well as image data. The proposed hardware algorithms exploit the principles of pipelining and parallelism in order to obtain high speed and throu... View full abstract»

    The author describes an algorithm for sample-rate conversion. Particular emphasis is placed on application of the algorithm for the conversion of the 1-b format as produced by a sigma-delta modulator into the PCM format. The algorithm permits subsampling before the major filtering operation and is therefore interesting for high-frequency applications such as A/D conversion of video signals. The al...

  • The optimum design of one- and two-dimensional FIR filters using the frequency response masking technique

    Publication Year: 1993, Page(s):88 - 95

    An expression for the impulse response up-sampling ratio M, which will produce a minimum complexity design, is derived. It is shown that M approaches e (the base of the natural logarithm) as the number of frequency response masking stages increases; in a K-stage design the complexity of the filter is inversely proportional to the (K+1)th root of the transition w...

  • Reply to `Comments on `Linearization Techniques for Nth-Order Sensor Models in MOS VLSI technology''

    For the original article see IEEE Trans. Circuits Syst., vol.38, no.12, p.1439-50 (1991). The author notes that the double-MOSFET method that was discussed in the above comment by Z. Czarnul (ibid., vol.39, no.9, p.677, 1992) is a design methodology relating the four-transistor circuit to a pair of voltage-controlled floating resistors and as such provides a systematic way to convert active-RC...

  • FFT butterfly network design for easy testing

    Publication Year: 1993, Page(s):110 - 115

    The authors consider offline testing and easily testable design of butterfly networks for fast Fourier transform. The butterfly networks are shown to be testable with 32 patterns using a design-for-testability technique based on the M-testability conditions. The functional-level cell-fault model is assumed, and the fault coverage for combinational single cell faults is 100%. A higher-level fault m... View full abstract»

  • On `global convergence' of Steiglitz-McBride adaptive algorithm

    The authors investigate the global convergence phenomenon of the Steiglitz-McBride adaptive identification/filtering method (SMM) observed previously under reduced order setting. Specifically, they relate the closeness of SMM solutions to minimum mean square error (MSE) points through sharpness of the MSE surface at these minima. They first define the sharpness, and then propose that generally glo... View full abstract»

  • Interpolation of 2-D signal by subsequence FFT

    Discrete interpolation between successive samples of a sequence is often required in digital signal processing. The subsequence approach for 1-D interpolation is extended to two dimensions to avoid redundant operations. An improved intermediate sequence is proposed to preserve the Hermitian symmetry in interpolating real-valued signals. The resulting algorithms is very efficient and convenient bec...

    A synthesis procedure for designing nonsymmetric cellular neural networks (CNN) with a predetermined local interconnection structure that will store a set of desired bipolar vectors as memory points is presented. A specific case of constructing Chinese characters is presented to demonstrate the applicability of the results. Simulation results show that all the vectors corresponding to 50 commonly ...
