Description
1. Simulate and plot the output response of the circuit depicted in Fig 1. Calculate ω0
and vary the resistor RD by using the follow values: 1 kΩ, 10 kΩ, 500 kΩ and 1 MΩ.
Explain the results obtained.

2. The circuit shown in Fig. 2 a Wein bridge oscillator. If R1 = R2, C1 = 0.1µF, C2 =
0.22µF and R4 = 10 kΩ, specify R1, R2 and R3 for the circuit to have stable oscillations
at f = 1000 Hz.
