Steady-state prediction in nonlinear circuits with periodic inputs by wavelet transform

The paper describes a method to predict steady states from transient states in nonlinear circuits with periodic inputs. The possibility of steady-state prediction from the transient state is shown if the wavelet transform is properly used. The discrete wavelet transform makes clear the variation of phase and frequency for characterising transient waveforms if the circuit has periodic inputs and the target for prediction is periodic. Additionally, a method is proposed to improve the time resolution, and the effects confirmed by an example
