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], R = 1k [math]\Omega[/math] (Note [math]R_L[/math] is the inherent resistance of the inductor).
  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 when r=0. (20 pnts)
  4. Measure the Gain when an external resistance (r) approximately equals to the inherent resistance of the rf choke [math]r \approx R_{L}[/math]. (20 pnts)
  5. Compare the measured and theoretical values of the resonance frequency ([math]\omega_{L}[/math]) (10 pnts)

Questions

  1. Determine the value of [math]R[/math] needed to have [math]V_{out} \approx V_{in}[/math] at resonance. (20 pnts)

Questions

  1. What is the current [math]I[/math] at resonance? (5 pnts)
