An Investigation of Kalman'S and Howitt'S Equivalence Transformations

摘要

Kalman's and Howitt's equivalence transformations are applied to the canonic impedance and admittance Foster LC forms and the Cauer ladder realizations for an RC circuit. The results provide a format for transforming from one realization to another directly. Application of the Kalman transformation to second-order Brune and Bott-Duffin realizations indicates that they are not compatible, implying the incompleteness of Kalman's transformation theory. The same technique is used to show a similar incompleteness of Howitt's theory. (Author)
