| two-terminal-pair network for which the sum of instantaneous powers at the two-terminal pairs is identically equal to zero and for which the ratio of the input voltage to the output electric current has a constant value R
NOTE 1 – For an ideal gyrator, the input voltage u1, the output voltage u2, the input current i1 and the output current i2 are related by the formula:
with the usual reference conventions for associated voltages and currents given for two-port networks in IEC 60375:2003, Clause 7.
NOTE 2 – Under sinusoidal conditions, the impedance Z1 seen at the input port is the product of the terminating admittance Y at the output port by the square of the constant R:
Z1 = R2Y
NOTE 3 – An ideal gyrator is a circuit element that neither stores nor dissipates energy. The gyrator as a device is defined in IEC 60050-726.
