Biquadratic, biquartic, bisextic, in general terms bi-order-n positive real immittance functions can be realized as driving-point immittances of a Tee or a Pi section that is terminated with a resistance, provided that the function belongs to a certain subclass of positive real and bi-order-n functions. This general principle is discussed particularly for biquadratic and biquartic functions. It is shown that the Tee and the Pi circuits implying a negative immittance of the rank 2m 1 can be transformed into another circuit that instead of the negative immittance implies a resistance as the only negative branch element.
