4–9

(a) Find an expression for the gain iO=vS in Figure P4–9 in terms of RX.

(b) Select a value for RX so that the gain is −0:002.

(c) Simulate the circuit in Multisim and perform a parameter sweep on RX from 10 Ω to 10MΩ and using the cursor to find the required value of RX. How does your answer compare with part (b)?
