Abstract :
Linear macromodels can be extracted from simulated or measured time domain responses using the Time Domain Vector Fitting (TD-VF) algorithm. In this paper we show that data preprocessing by means of a digital filter (FIR) can reduce the model order and avoid false oscillations in the model´s response. The procedure is demonstrated for the modeling of a cable from simulated data and for the modeling of power transformers from measurements.
