(b) Choose appropriate resistance values for the two resistors R₁ and R2 for an expected voltage gain of 20. Relevant calculations and practical considerations should be given. (c) State the input and output resistances of the amplifier circuit in Figure 4.1 by assuming the op-amp in the circuit is ideal. Explain briefly how the input resistances of the circuit may be improved.
