Abstract: This circuit constant variable circuit changes the circuit constant of a passive element for which the impedance fluctuates according to the frequency of an AC current. The circuit constant variable circuit is equipped with a first bidirectional switch (Q1) connected in series, a series circuit (20) including a passive element (C1), and a second bidirectional switch (Q2) connected in parallel to the series circuit (20).
