Analysis method of periodic solution using Haar wavelet transform for autonomous nonlinear circuits

Recently, much attemtion has been paid to the methods for circuit analysis using wavelet transform. In particular, we have proposed the analysis methods using Haar wavelet transform. Haar wavelet can be easily treated, be adapted to time varying and nonlinear circuits and we can be easily derived differential and integral operator matrices by using block pulse functions. Furthermore, it can analyze a region near singular points more precisely. Therefore, we consider that it is suitable to analyze nonlinear time-varying circuits. In this paper, we propose the method to analyze the numerical solution of the periodic solution of the autonomous nonlinear circuit.
