    The associative memory of a stack filter is defined as the set of root signals of that filter. In a class of stack filters in which each filter's root set contains a desired set of patterns, those filters whose root sets have the smallest cardinality are said to be minimal among all filters in that class for that set of patterns. A partial ordering is defined on the set of stack filters via the se... View full abstract»

    The classical state-space approach to continuous-time spectral factorization is used to develop a method for discrete-time spectral factorization. This results in a quadratic matrix equation which is referred to as the modified algebraic Riccati equation (MARE). Solving this equation for the factorizing solution constitutes the major part of the computation needed to obtain the spectral factor. Re... View full abstract»

    It is shown that if the phase of the bispectrum corresponding to a nonminimum phase system has a 2 kπ change at some frequencies, which will not affect the value of the bispectrum, many algorithms proposed for the phase reconstruction of the system transfer function from the bispectrum will give an erroneous result. To solve the problem, an algorithm that can suppress the effect of the... View full abstract»

    A BiCMOS programmable frequency divider which is a major functional block of a frequency synthesis IC based on a phased-locked loop is described. Innovative techniques are demonstrated to solve many incompatibility problems between ECL and CMOS techniques. It is shown that a similar concept can be applied to other high-speed designs. The frequency divider has 15 stages and operates at 165 MHz. It ... View full abstract»

    Efficient methods for mapping odd-length type-II, type-II, and type-IV DCTS to a real-valued DFT are presented. It is found that odd-length type-II and type-III DCTs can be transformed, by means of an index mapping, to a real-valued DFT of the same length using permutations and sign changes only. The real-valued DFT can then be computed by efficient real-valued FFT algorithms such as the prime fac... View full abstract»

    An effective eigenfilter approach is proposed for designing FIR filters with complex-valued frequency responses. By minimizing a quadratic measure of the error in the frequency band, an eigenvector of an appropriate matrix is computed to get the filter coefficients. The algorithm is easy and optimal in the least squares sense; it is used to design to major classes of FIR filters, including multiba... View full abstract»
