    The cross-Gramian matrix W_{c0} (T) for linear single-input single-output (SISO) dynamical systems has been related to the controllability and observability Gramians via W^{2}_{c0}(T)= W_{c}(T)W_{0}(T) for T= \infty . The result is now proved for any arbitrary time interval View full abstract»

    This paper describes an approach to yield estimation which has been developed specifically for large circuits and systems. The approach is based upon the partitioning of a given system into subsystems and is developed in terms of integral transforms. Efficient computational schemes are described which are developed from the properties of the transforms and some elementary ideas from mathematical s... View full abstract»

    It is shown that the approximation problem for minimumphase FIR filters with arbitrary specifications on the attenuation can be solved by a method published in [3] although that method is based on the same idea of that developed in the above footnote[1]{paper}, it is simpler and also easier to apply.

    This paper investigates a systematic suboptimal approach to multilayer rectilinear wire routing: the single row approach. The method involves decomposing the general rectilinear wiring problem into a number of conceptually simpler single row problems. The complexity of the decomposition process is first considered. Under interesting optimization criteria, each step in the decomposition process is ... View full abstract»

    This paper presents a practical approach for, cancelling a periodic interference from signal measurements. In the method the waveform of the interference is continuously estimated and subtracted from the measurement. The rejection properties are made independent of small variations in the fundamental frequency of the interference by fixing the sampling rate to be an exact multiple of it. Special a...

  • CAD modeling of three-terminal piecewise-linear device characteristics

    Publication Year: 1984, Page(s):500 - 503

    The purpose of this work is to construct a circuit analysis model synthesizing piecewise-linear characteristics of a three terminal device, using only two-terminal piecewise-linear resistors together with linear controlled sources. The model is based on representing the function, to be modeled, by a finite amount of tabulated data. View full abstract»

    In the analysis of large systems such as high-speed digital computing networks and circuits on an LSI or VLSI silicon chip, lossy lumped-distributed networks have been used to model their interconnections. A solution of the synthesis problem for these networks will aid in the design of these circuits. This paper establishes single-variable realizability conditions and synthesis procedures for the ...

    Root distribution of real coefficient polynomials with respect to conic subregions in the complex plane, is determined by a standard half-plane test on a transformed polynomial. A unified approach to derive the pertinent transformation for a given conic curve by using its description in polar coordinates, is described. Specific transformations and root distribution criteria are given for a left pa... View full abstract»

    Error spectrum shaping (ESS) can significantly reduce finite-wordlength error in recursive fixed-point digital filters. Most past work on ESS has focused on second-order filters. In this paper, expressions for the ESS coefficients minimizing the roundoff error are derived for high-order filters composed of cascaded second-order sections. A comparison of the noise gains is made between optimal and ... View full abstract»

  • FIR low-pass filter design using parametric filter technique

    This paper describes a new design method for finite impulse response (FIR) filters. FIR low-pass filters which have quasi-equiripple characteristics in the stopband and arbitrary ones in the passband are designed. Applying the parametric filter design technique, the stopband zeros are given in the closed form. Hence, only passband zeros are iteratively approximated to shape passband characteristic...

    The Residue Arithmetic Adaptive Filter (RAAF) processor performs the least mean square (LMS) algorithm using 60 ns discrete PROM-latch combinations for the residue operations. Parallel and pipeline techniques are used throughout. Since the LMS algorithm is recursive, scaling is required between filter iterations. The scaling penalty has been eliminated by the use, of a new residue scaling techniqu... View full abstract»
