Abstract
The fault analysis of sine and linear frequency modulated signals using wavelet transform is proposed in this paper. By using the wavelet transform, the time-frequency localization characteristics and the frequency information of waveform can be integrally obtainable. This approach is more efficient in monitoring the time-varying disturbances when compared with those of fourier transform based methods. In this paper, the result analysis shows how the decomposition of sine and linear frequency modulated signals has been carried out by using wavelet transform.

Reduced Wirelength-Based Low Power Performance of Multibit Flip-Flop

Volume 1 Issue 4 September - November 2013 Research Paper Reduced Wirelength-Based Low Power Performance of Multibit Flip-Flop M.Karthick*, S. Vijayakumar** *PG Scholar, Department of Electronics and Communication Engineering, Paavai Engineering College, Namakkal, India. **Associate Professor, Department of Electronics and Communication Engineering, Paavai Engineering College, Namakkal, India. Karthick, M. and Vijayakumar, S. (2013). Reduced Wire length-Based Low Power Performance Of Multibit Flip-Flop.  i-manager’s Journal on Circuits and Systems , 1(4), 22-26.  https://doi.org/10.26634/jcir.1.4.2593 Abstract Power reduction is a main parameter to design VLSI circuits. In this paper, to design a number of D-flip flop performing at the same time, the given clock signal is reduced using multi bit flip-flop. The multi bit flip flop is mainly used to improve the clock power for the given common clock signal and to reduce the switching power. This method is p...
