LC Resonance circuits
The LC cicuit
- Design a parallel LC resonant circuit with a resonant frequency between 50-200 kHz. use = 10 - 100 .
- Construct the LC circuit using a non-polar capacitor
- Measure the Gain as a function of frequency.
- Measure the Gain when you insert an external resistance approximately equal to the inherent resistance of the rf choke .
- Compare the measured and theoretical values from the resonance frequency () and the Quality factor value for each case; .
