    A new activeRCnetwork synthesis procedure is presented. The realized network suitable for hybrid film fabrication contains the minimum number of capacitors and only four operational amplifiers in an active controller for the synthesis of annth-order voltage-ratio transfer function. The amount of controller gain is minimized by the selection of the optimal feedback and input t... View full abstract»

    This article describes the implementation of a modular fast Fourier transform (FFT) processor for real-input applications. The nature of the signal has been exploited to reduce to a minimum the number of multiplications and the calculations are performed in an ordered sequence in order to evaluate only the nonredundant terms at each pass. The number of components required for transformingN View full abstract»

    A proposed method for testing printed circuit boards for the existence of possible (undesired) short circuits transforms the test minimization problem into one of finding minimum vertex colorings of certain special graphs, called line-of-sight graphs. Under certain assumptions on the possible types of short circuits, we analyze the structure of such graphs and show that a well known and efficient ... View full abstract»

    The solution of electric network problems by various algorithms such as for example Newton's method is often hampered by the presence of physical diodes with steeply rising exponential characteristics which cause overflow and slow convergence during numerical computation. In this paper we propose and analyze an algorithm which bypasses these difficulties by successively approximating the steep dio... View full abstract»

    In this letter, we comment on a bordered triangular form (BTF) of an irreducible matrix introduced by Cheung and Kuh, and present other relevant references concerning a BTF matrix and the use of topological rules for finding a minimum essential set of a digraph. View full abstract»

    This paper presents a universal structure for wave digital filters. These universal structures can be modified to achieve any desired digital frequency specifications by simply changing the value of the structure multipliers without altering the overall structure. Utilizing these structures, it becomes feasible to realize digital filters with simultaneously varying bandwidth and center frequency. View full abstract»

    The noise characterization of linear circuits is discussed in connection with the transformation of the noise parameters. The noise performance of two-ports is treated, as are methods for linear devices including correlated, uncorrelated, and partially correlated noise sources. Finally, the experimental determination of the noise parameters is described. Special attention is given to negative sour... View full abstract»

    The second-order approximated solution of a negative resistance oscillator whose active device has a piece-wise analytical characteristic is presented. The frequency and the harmonic content of the oscillation waveform are obtained as functions of the circuit parameters and of the device bias. View full abstract»
