    The Implementation of Nonlinear Dynamical Systems With Wavelet Network
    (Urban und Fischer Verlag GmbH und Co. KG, 2006) Özkurt, Nalan; Savacı, Ferit Acar
    A dynamic wavelet network circuit implementation for modelling the nonlinear dynamical networks has been proposed in this study. The dynamical wavelet network includes static wavelet network with Mexican hat wavelet function, the voltage-controlled switches and capacitors. The circuit simulations have been done in Spice for the period-1 limit cycle, the spiral and double scroll attractors of the Chua's circuit.

    The System Modelling and Circuit Implementation From Time-Frequency Domain Signal Specifications
    (Urban und Fischer Verlag GmbH und Co. KG, 2008) Savacı, Ferit Acar; Özkurt, Nalan
    The system modelling and the circuit implementation of the nonlinear circuits using the wavelet domain techniques has been accomplished in this study. When the time-frequency domain specifications have been given as the wavelet ridges, the signal with the given ridges has been synthesized. Then, the dynamical wavelet network has been trained for the synthesized signal. The circuit of the wavelet network has been designed and simulated. © 2007 Elsevier GmbH. All rights reserved.

    The Circuit Realization of Mexican Hat Wavelet Function
    (Urban und Fischer Verlag GmbH und Co. KG, 2005) Özkurt, Nalan; Savacı, Ferit Acar; Gündüzalp, Mustafa
    A wavelet network circuit implementation for Mexican Hat mother wavelet has been proposed for nonlinear function approximation which can also be used for the realization of the algebraic nonlinear components. The Mexican Hat mother wavelet function has been implemented with discrete circuit components and it has been observed that the experimental waveform obtained from the realized circuit is approximately same as the Spice simulation of the original function. The circuit simulations of exemplar functions implemented in Spice are also given. © 2004 Elsevier GmbH. All rights reserved.
