- Present 2 equivalent RCL circuits (for R6 = 0Ω and R6 = 10kΩ).
- Find a resonant Frequencies f0min and f0max (for R6 = 0Ω and R6 = 10kΩ).
- Find value of Q for both frequencies.
- Simulate the circuit in the frequency’s range f between 1 and 10,000 Hz. Use Vin=100 mV (RMS);
- Present result in form of Vout / Vin = F(f) for 2 simulations (for R6 = 0Ω and R6 = 10kΩ) on the same logarithmic graph.
