    In this paper, a simple control method is proposed for stabilizing unstable equilibria of two typical classes of chaotic systems. For piecewise-linear chaotic systems, such as Chua's circuit, the control parameters can be selected via the pole placement technique from the linear control theory. For general nonlinear chaotic systems with continuously differentiable nonlinearities, particularly poly... View full abstract»

    A new differential integrator implemented using current feedback amplifiers (CFAs) is presented in this paper. The resulting integrator is stable and does not employ a capacitor in the negative feedback path of the CFA for its operation. Experimental results taken from AD844 CFAs authenticate the viability of the proposed integrator. View full abstract»

    A method to generate a Nyquist pulse using a maximally flat delay polynomial for the denominator of the transfer function and an appropriate placing of the zeros of the numerator is described. The transmission zeros are chosen so that the resulting pulse outperforms the raised-cosine pulse in terms of the least-mean-square (LMS) timing error and timing jitter. The resulting transfer function is re... View full abstract»

  • Log-domain wave filters

    A systematic method for designing log-domain wave filters is presented. Wave filters simulate topologically and functionally passive doubly terminated LC ladder prototype filters of low sensitivity. The design in the log-domain is based on a transposition of the signal flow graph (SFG) that corresponds to the wave equivalent of elementary two-port blocks in the linear domain, to the corresponding ...

  • A mixed-signal approach for tuning continuous-time low-pass filters

    A mixed-signal approach for tuning the bandwidth of continuous-time low-pass filters is presented. The tuning loop uses common circuit blocks (a data converter and digital filters). Simulation results are presented for a number of filters, and measured results are presented for tuning second-order and fourth-order filters. View full abstract»

  • Capacity of stable periodic solutions in discrete-time bidirectional associative memory neural networks

    The existence, stability, and even the number (capacity) of stable periodic solutions in discrete-time bidirectional associative memory neural networks are investigated in this paper. Some fundamental mathematical techniques instead of the bifurcation method, are employed to prove the existence of periodic solutions and establish the relation of the number of periodic solutions and the magnitude o...

  • Robust filtering under randomly varying sensor delay with variance constraints

    This paper deals with a new filtering problem for linear uncertain discrete-time stochastic systems with randomly varying sensor delay. The norm-bounded parameter uncertainties enter into the system matrix of the state space model. The system measurements are subject to randomly varying sensor delays, which often occur in information transmissions through networks. The problem addressed is the des... View full abstract»

    This paper is concerned with the optimal steady-state estimation for singular stochastic discrete-time systems using a polynomial equation approach. The key to the optimal estimation is the calculation of an optimal estimator gain matrix. The main contribution of the paper is the derivation of a simple method for computing the gain matrix. Our method involves solving one simple polynomial equation... View full abstract»
