Abstract
A detailed knowledge of amplifier transmission characteristics is important in many technical areas, for instance in commercial modeling systems as the Simulink. The paper shows that a good approximation of measured amplitude and phase characteristics can be made numerically by a rational function. If there is enough computation time, the complex transfer characteristic can be well approximated. Then zeros and poles can be found. Preliminary calculation reveals that the tested amplifier is not a minimum phase network.
