LC Resonance circuits

The LC cicuit

1. Design a parallel LC resonant circuit with a resonant frequency between 50-200 kHz.
2. Construct the LC circuit using a non-polar capacitor
3. Measure [math]\frac{V_{out}{V_{in}}[/math] as a function of frequency.
4. Measure the ratio when you insert an external resistance approximately equal to the inherent resistance of the rf choke [math]R_{L}[/math].
