State equations in the Haar domain

Haar wavelet transform has already been applied to time-variant circuit analysis. In particular, examples have been developed for RL transients and power converter simulation. Here a new wavelet-based identification method is proposed. The aim of the new approach is to give a dynamical analysis of the Haar spectra. The whole transient of a square wave fed RL load has been considered, and parameters have been identified through an iterative procedure.
