Operational Amplifier (Op-Amp) is a solid-state device with voltage amplification capabilities as shown in Figure Q1. (a) Name the function of Op-Amp U1, U2 and U3 in Figure Q1. (b) Derive the output voltage (Vol, Voz and Vo3) of each Op-Amp in Figure Q1. Based on derivation in Q1(b), calculate the output voltages (Vol, Vo2 and Vo3) of the circuit. All the Op-Amps are powered with + 12V voltage supplies. Given: Ra = Rb = 1 kN, Ry = Rx = 10 kN, Ra = 3.6 kN, Rr = 3 k2. The input voltages: V,= V = 5 V. (c) (d) Draw and label clearly the sinusoidal output of Vo1, Vo2 and Vo3.
