GIC as part of tunable band-pass filter.

Given:

R1 = 1.0 kΩ;
R2 = 1.0 kΩ;
R3 = 1.0 kΩ;
R4 = 1.0 MΩ;
R5 = 1.0 kΩ;
R6 = 10 kΩ;
C1 = 1000 μF;
C2 = 1 μF;
VCC = ± 12 Volt;

OA1, OA2 - 741

- 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.
