Which two-port device has a provision to simulate the equivalent values of inductance?

a. Inductor

b. Capacitor

c. Transformer

d. Gyrator

ANSWER: Gyrator

Explanation:

Gyrator is a four terminal device whose coefficient value is dependent on the Op-amp parameters as well as externally connected R,C values.

It exhibits a unique feature of impedance inversion phenomenon due to which the input impedance is capacitive for an inductive load impedance and vice-versa. In addition to this, simulation of equivalent inductance values is also a major function performed by a gyrator
