Abstract

A variable reactance circuit which can produce equivalent reactance varying from negative given values to positive given values in accordance with fundamental reactance elements such as capacitor, coil, etc. The present invention has a big advantage of being capable of easily producing the positive, negative equivalent reactance given times as much as the basic reactance element with the use of a circuit which can be integrated.
