A novel scheme for the analogue implementation of wavelet transform (WT) using discrete time switched-current (SI) filters is presented. An excellent approximation of the mother wavelet is given by differential evolution (DE) algorithm. The WT circuits consist of the filters whose impulse response is the approximation of the required wavelet. The wavelet filters are designed by a parallel structure...
For applications requiring low-voltage low-power and real-time processing, a novel scheme for the VLSI implementation of wavelet transform (WT) using switched-current (SI) circuits is presented. SI circuits are well suited for these applications since the dilation constant across different scales of the transform can be implemented, and controlled by both the aspect-ratio of the transistors and the...
A novel method for fault diagnosis of analog circuit based on chaos differential evolution wavelet neural networks (CDE-WNN) is proposed in this paper. In order to simplify network architectures and improve its learning accuracy and convergence rate, the architectures and parameters of wavelet neural networks are optimized by chaos differential evolution algorithm in the method. The fault dictionary...
