Question

Figure 1(a) shows a voltage subtraction amplifier where its inputs, V_O1 and V_O2 are from the circuit of Figure 1(b) and Figure 1(c) respectively. Determine the output voltage, V_O, given that R_f= 20 kΩ, R₁ = 10 kΩ, R₂ = 5 kΩ and R₃ = 2.5 kΩ whereby inputs, V_i1 = 4m sin (1000t)V and V_i2=10m sin (1000t)V.

1. Refer Figure 1(c), calculate output for the op-amp 1:

V₁ = m sin 1000t

2. Refer Figure 1(c), calculate output for the op-amp 2:

V₂ = m sin 1000t

3. Refer Figure 1(c), calculate output for the op-amp 3:

V₃= m sin 1000t

4. Refer Figure 1(b), calculate V_o2 :

V_o2= m sin 1000t

5. Refer Figure 1(a), calculate V_o :

V_o = m sin 1000t
