- Present two equivalent RCL circuits (for R₆ = 0Ω and R₆ = 10kΩ).
- Find a resonant Frequencies f_0min and f_0max (for R₆ = 0Ω and R₆ = 10k)
- Find value of Q for both frequencies.
- Simulate the circuit in the frequency's range f between 1 and 10,000 Hz. Use Vin = 100mV (RMS);
- Present result in form of Vout/Vin = F(f) for 2 simulations (for R₆ = 0Ω and R₆ = 10 kΩ) on the same logarithmic graph.
