Question 2 Figure 1 shows the voltage-divider bias configuration. Consider RE is bypassed by an emitter capacitor, C3. Answer the following question: ch Rs = 0.3 k Z₁ C₁ E www Rc = 2.2 kn RB1 = 68 kn RB2 = 16 kn C₂ H Figure 1 Zo N B110, ro 20 ko = C3 6 RE= 0.75 k lo RL=4.7 k0; Vcc = 16 V (45 marks) a) Construct the ac equivalent network for the voltage-divider bias configuration. b) Calculate the overall voltage gain, Avs for the network in Figure 1. c) Change R₁ to 5.6 k and calculate Avs. Justify your answer on the effect of increasing levels of R₁ on the gain. d) Change Rs to 1 ks (with R₁ = 4.7 ks) and calculate Avs. Justify your answer on the effect of increasing Rs on the gain.
