The Gyrator as a 3-Terminal Element

A 3-terminal circuit element, that has properties similar to those of a gyrator, is described. A method is derived to realize such an element with any unilateral transducer such as a vacuumtube or a transistor. The effect of loading a gyrator by admittors in parallel or in series with its terminals is investigated. It is also shown that suitable loading of a gyrator may transform it into another gyrator of different gyrating admittance.
