Special cases of Fliege´s complementary transformation for active RC networks

A transformation is given which consists of the application of Fliege´s complementary transformation in a special way to a network of restricted topology. Since the transformation is a special case of Fliege´s transformation, it does not alter the denominator of the network´s voltage transfer ratio. However, whereas in Fliege´s general transformation the numerator has to be determined by circuit analysis, in the new transformation the numerator is given directly. The application of Hilberman´s transformation to the transformed network leads to an alternative transformation with similar properties.
