Positive real and biquadratic immitance functions F(s) are realized into three groups each consisting of two times six equivalent circuits. The first group is o

It is shown that a positive real immittance function F(s) is of one of eight categories. The category can be recognized by the sign polarities of three test val

The paper presents a novel technique for computing the elements of the Brune realization and of the Bott-Duffin realization of a bi-order-n and positive real im
