LC Resonance circuits

The LC cicuit

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