I am asking for a solution branchs C & D
Activity # 2
You have to study the effect of the type of feedback on building op amp applications using 741 op-amp.
A) Discuss the circuits in Figure 2 using the 741 op-amps and the biasing voltage of 10V. Assume R1 and R2 are equal. Build both circuits virtual and the lab and compare the out results having an input sinusoidal of 8V amplitude and 1kHz frequency.
B) Explain the principle of operation of Figure 2. Explain limitations of both circuit in terms of practical applications. What is the technical name describing this circuit? What are the reference voltages in both circuits
C) Explain the principle of operation of the op-amp in the first stage of Figure 1. What is the advantage of this circuit compared to Circuits in Figure 2? What is the technical name describing this circuit?
D) Explain the principle of operation of the op-amp in the last stage of Figure 1. What is the advantage of this circuit compared to Circuits in (A) and (C)? What is the technical name describing this circuit?
