Reconstruction of Nonstationary Signals Along the Wavelet Ridges
(World Scientific Publishing Co. Pte Ltd, 2006) Özkurt, Nalan; Savacı, Ferit Acar
In this paper, the nonstationary signals have been recovered using the skeleton along the wavelet ridges in the noisy case and the attractors of the cleaned signals are reconstructed in the phase space by time-delay embedding. In order to verify the signal recovery and reconstruction procedure, the similarity measure Hausdorff distance between cleaned, noise-free original attractors have been calculated. The computations show that the procedure reduces the noise level acceptably and the reconstructed attractors are more similar to the original attractors.

The Circuit Implementation of a Wavelet Function Approximator
(Springer Verlag, 2002) Özkurt, Nalan; Savacı, Ferit Acar; Gündüzalp, Mustafa
This paper describes the analog synthesis of a wavelet function approximator using sigmoidal mother wavelet. Any finite energy multivariate function can be approximated by this analog circuit using the multiresolution approximation property of the wavelet decomposition. The approximator circuit includes bipolar junction transistors, operational amplifiers and linear passive circuit elements.
