Gyrator-tuned Ferrite Antenna
Potentiometer replaces tuning capacitor
Gyrator circuits can be used to simulate capacitors and coils. What’s more, they can also be used as impedance converters, as described in this article. After that we will see how a gyrator can be used to tune a ferrite rod antenna.
