LC Resonance circuits
The LC cicuit
- Design a parallel LC resonant circuit with a resonant frequency between 50-200 kHz. use [math]\displaystyle{ L }[/math] = 10 - 100 [math]\displaystyle{ \mu H }[/math].
- Construct the LC circuit using a non-polar capacitor
- Measure the Gain [math]\displaystyle{ \equiv \frac{V_{out}}{V_{in}} }[/math] as a function of frequency.
- Measure the Gain when you insert an external resistance approximately equal to the inherent resistance of the rf choke [math]\displaystyle{ R_{L} }[/math].
- Compare the measured and theoretical values from the resonance frequency ([math]\displaystyle{ \omega_{L} }[/math]) and the Quality factor [math]\displaystyle{ Q \equiv 2 \pi \frac{W_S}{W_L} = \frac{\mbox{Energy Stored}}{\mbox{Energy Lost}} }[/math] value for each case.
