Abstract

The second impedance element is a three-terminal impedance network whose effective conductance between and the first and the second terminal, and between the first and third terminal is so variable, that when the effective conductance between the first and third terminal increases from zero to a specified value, the conductance between the first and second terminal decreases from the specified value. It comprises a first null or with a first nullator so connected, that it maintains the second and a further terminal at the same potential, and a first norator connected to the second terminal. One of the two impedance elements is a load, and the other a current divider which directs through the load a part of the total current in the variable two-terminal impedance.
