Comment on homographic transformation for the simplification of continuous-time transfer functions by Padé approximation

T. Nigel Lucas

Research output: Contribution to journalArticle


It is shown that the homographic transformation method for reducing the order of linear, time-invariant systems produces the same models as the ordinary Pad approximation method about 8 = 0, contrary to what was previously thought. An example is given to demonstrate the equivalence of the methods.
