b) For correct operation as an ac amplifier a npn BJT must be correctly DC biased to establish an appropriate Q-point, i.e a negative voltage VBC between the base and collector terminals and a positive voltage VBE between the base and emitter terminals. Figure 3.1 shows a circuit that can achieve this requirement. Explain the role of each resistive element in this circuit.
