Q.  Which two-port device has a provision to simulate the equivalent values of  inductance? (Marks : 01)
- Published on 19 Oct 15

a. Inductor
b. Capacitor
c. Transformer
d. Gyrator

ANSWER: Gyrator
 
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
