Modelling and measurement of nonlinear amplifier system
MA Aseeri, M.I. Sobhy · 2001
Abstract: An improved model for non-linear amplifiers (NLA) is presented using the MATLAB® software. The model is identified from time domain measurements. Time domain modelling, simulation and frequency domain characteristics are used throughout the procedure. The Modelling of non-linear amplifier is divided in two subsystems, obtained by pulse measurement which offers considerable saving in measurement time. The derived model is not based on an equivalent circuit and offers flexibility and saving in the amount of data stored and in simulation time. 1.
